LCD LED CRT Power Consumption

Display power consumption

 

I picked up a Kill-a-Watt a while back in hopes of learning more about energy consumption - how much does a second hard drive, increased RAM, or adding a USB 2.0 card increase the current draw on my G4 Power Macs. I'll get to that eventually, but I have done some testing of computer displays - and made some interesting discoveries.
The first one I tested was a 17" Gateway 2000 Vivitron 1770 that I picked up at a moving sale for $3. Who can resist that kind of price? I wondered if it might draw less power than my current monitor, and the Energy Star sticker was encouraging.
My Blue & White Power Mac G3 booted to 800 x 600 resolution at 60.3 Hz, and the Kill-a-Watt reported the display was drawing 90W. Bumping resolution to 1024 x 768 @ 60 Hz, that dropped a bit to 88W. Changing the refresh rate to 70 Hz increased that to 92W. This display has an 1152 x 870 setting - at 75 Hz, it draws 97W. Finally, at 1280 x 1024 and 60 Hz, that drops a bit to 95W. And when Energy Saver puts the display to sleep, elecricity usage drops to 3.6W.
This is an older monitor, not especially crisp, and slow to wake up, but it's a contender for use on a server, where it will only be powered on when necessary. The 1152 x 870 75 Hz setting is a good compromise between resolution and a steady display. (60 Hz tends to create a subtle flicker that can tire your eyes over time.)

Not bad for $3 - and I also got a free 15" 10-year-old Dell E550 at the same moving sale. It draws a whole lot less power - between 49 and 55 Watts in my various tests. Here's the quick overview:
800 x 600 @ 60 Hz, 49.4W; 75 Hz, 52.5W; 85 Hz, 54.8W
1024 x 768 @ 60 Hz, 51.6W
640 x 480 @ 60 Hz, 49.2W; 75 Hz, 50.6W; 85 Hz, 52W; 100 Hz, 54.2W

Interesting pattern: The higher the refresh rate and/or resolution, the greater the power draw - but not by a huge amount. There's only about 10% variance among the settings I tested.
This monitor also has one big plus over the Gateway Vivitron - the power button is up front, making it easier to turn it on and off. Thank goodness most displays moved away from rear-mounted power buttons years ago.

The third display I tested is an ancient Compaq 15" from the mid-to-late 90s. I picked up a few of these refurb at a very good price. They're not great monitors, but okay for setting up computers and testing. I was the same pattern in energy usage:
640 x 480 @ 60 Hz, 67W; 75 Hz, 71W
800 x 600 @ 60 Hz, 69W; 75 Hz, 74W
1024 x 768 @ 60 Hz, 73W
With Energy Saver putting the display to sleep, this drops to 14.5W - a lot more than the 17" Gateway Vivitron.

I next tested a 17" Micron display that my wife used to use with her Windows PC. No matter what resolution and refresh rate I chose, power draw was steady at between 118.5 and 119W. That surprised me after my other tests.
My stock CRT display for years has been a Samsumg 700DF, which supports up to 1280 x 1024 pixels. I've used it with my Titanium PowerBook and various G4 Power Macs, most recently with the dual 1 GHz Mirror Drive Door model. The display is crisp, but the refresh rate at 1280 x 1024 is a low 60 Hz. At tested resolutions and refresh rates, it consistently measured 120W.
By contrast, my 19" Dell flat panel display draws just 26W at its native 1280 x 1024 resolution. This is my primarly display - easy on the eyes, good resolution, and it sold for a great price when I bought it many years ago.

You can save quite a bit of energy by choosing the right display. The flat panel beats the CRTs hands down, the 15" Dell CRT draws about 30% less than the even older Compaq, and the Gateway Vivitron saves 20-25% over the Samsung and Micron monitors I tested.
End result: Until I can afford a new flat panel display, I'll keep the 19" Dell flat panel as my primary display on my Leopard machine (1.6 GHz dual G4 upgraded Digital Audio Power Mac), the Samsung on my Mirror Drive Door (the Gatewaw draws less power, but it's not crisp, wakes from sleep slowly, and has poorer color). On my server, I'm going to hook up the 15" Dell E550, which uses less energy than any of the CRT displays I've yet tested. I'll run it at 1024 x 768, which is lower than I prefer, but then I'm really only using this dual 500 MHz Power Mac G4 as a servery, so it's not a big deal.

Number Crunching

 

Electical rates range from 12¢ to 15¢ per killowatt-hour here in Michigan. By using a flat panel display instead of a 17" CRT, I save between 69 and 94 Watts - say an average of 85. That's roughly 2.04 kWH per day, 61 per month, for a saving of $7.30 to $9.20 a month, ignoring things like sleep mode and Energy Saver settings.
But you probably don't run your monitor 24/7. Let's say you have your monitor on 8 hours a day, 5 days a week, and you're using it enough so sleep mode rarely kicks in. 22 workdays in a month times 0.68 kWH per day comes out to 14.96 kWH per month. Savings: $1.80 to $2.25 per month in this scenario - $22 to $27 a year.
Ballpark figure: If you're using a 17" CRT and replace it with a 19" to 22" flat panel display, you may reduce your electric bill $20 a year assuming a 40 hour work week - or  $100 assuming the display is on 24/7. Use that display for 5 years, and you've saved between $100 and $500, probably enough to justify that $99 flat panel display Dell had on clearance last week or that $160 22" 1080 x 1920 display you discovered on dealmac.

Other benefits of going flat panel: No flicker, so it's easier on the eyes, and crisp pixels, where CRTs can become fuzzy over time. Less heat. And you'll have all those extra pixels to play with if you go widescreen. I find a 1080 x 1920 display very tempting, as I often have a dozen or more apps active at once, lots of overlapping windows, and the extra screen width would be a real blessing. (I've tried 1440 x 900 displays. After years at 1280 x 1024, I miss the extra height. Going to 1080 makes things even better.)
You'll need to do your own number crunching for your display, the new one you're looking at, monthly usage, and your local electrical rate. Just be sure to do your due diligence before you buy a new monitor - find out what reviewers and end users have to say about things like color accuracy, glare, build quality, etc.

10 energy-efficient computing tips

The following is a list of 10 energy-efficient computing tips from TechSoup and Climate Savers Computing to help guide your IT habits in 2010:

1. Use computer and monitor power management. Doing so can save nearly half a ton of CO2 and more than $60 a year in energy costs.
2. Don’t use a screen saver. Screen savers are not necessary on modern monitors, and studies show they actually consume more energy than allowing the monitor to dim when it’s not in use.
3. Buying a new computer and/or monitor? Make energy efficiency a priority while shopping for your PC and monitor. Buy EPEAT rated new computers, or if you buy from a retail store, look for the ENERGY STAR label or browse the Climate Savers Computing product catalog.
4. Buy refurbished computers if you mostly do basic things on computers like word processing, Internet browsing, e-mail, and downloading/uploading digital photos. Refurbished computers cost less than new computers and extend the life of IT equipment. The U.S. EPA Electronics Environmental Benefits Calculator finds that it is roughly 25 times more beneficial environmentally to reuse desktop computers than to recycle them at three to five years of age.
5. Turn down the brightness setting on your monitor. The brightest setting on a monitor consumes twice the power used by the dimmest setting.
6. Turn off peripherals such as printers, scanners and speakers when not in use. You can use smart power strips, which automatically turn off your accessories when you shut down your computer — or plug all your electronics into one power strip and turn the strip off when you are finished using your computer.
7. Use a laptop instead of a desktop. Laptops typically consume less than half the power that desktops use.
8. Use rechargeable batteries in IT devices like digital cameras. They are now low-cost, have long life, save you money and reduce toxics in landfills.
9. Use a power meter like Verdiem's free Edison application to find out how much energy your computer actually consumes and to calculate your actual savings.
10. Recycle your old electronics (anything with a plug), batteries, CFLs and ink cartridges. Reduce toxics in landfills. You can learn how to recycle electronics and find recycling centers here.

LCD VS CRT Monitor Comparison

LCD vs. CRT Monitor Comparison

 

Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Monitor's size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy.

However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor. Viewing Direction: A CRT screen can be viewed from all directions. And from different distance. But LCD monitors cannot be viewed from all directions. LCD monitors can only be viewed straight. Therefore its viewing direction is limited. If viewed from other directions the colors will change and sometimes the vision will be unclear if not viewed straight. But in recent years the new LCD monitors have improved on this defect. Radiation Emission: The radiation emission in CRT monitors are higher. This will not be visible normally but it will affect eyesight and may cause head ache. Long term use of these monitors may even affect the eyes adversely. LCD monitors do not have this type of Radiation emission. Therefore LCD monitors are good for the eyes. Price: CRT monitors are priced very cheap. However they consume more power. LCD monitors are priced higher, but they consume less electricity. Though the electricity consumption is not very significant for personal use, it is very cost efficient in big organizations with many computers.

LCD Monitor
Text and images (scans of census records) are crisper and sharper and the LCD monitor is easier on your eyes. Dot pitch: This is the space between dots and is measured in fractions of a millimeter, e.g., .25mm. The smaller the number the better because the dots are tighter. Many manufacturers don%u2019t even list the dot pitch anymore and you probably won%u2019t be able to tell the difference between a .22 and .27 pitch anyway. So, if you like the monitor then don%u2019t worry about the dot pitch. Passive-matrix vs. active-matrix: Do not buy a passive-matrix monitor. I seriously doubt you%u2019ll even see one for sale, but%u2026just in case. Having said that, there are some new passive-matrix technologies that are worth buying. If the monitor isn't TFT (a type of active-matrix), look for CSTN or DSTN (the latest passive technologies). Brightness: How bright is the picture, expressed as cd/m (I have no idea what the units mean). Look for a brightness level of 200 cd/m or greater. Again, if the monitor specs don%u2019t list this value (not all do) be sure you can get your money back. If the lighting in your office (kitchen table) is subdued the brightness factor won%u2019t be as important as if you have a lot of sunlight streaming in. Don%u2019t pay extra for extra brightness unless you%u2019re worried about bright sunlight. Overall, the contrast ratio will have a bigger impact on picture quality. Monitor's size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy. However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size. Resolution: CRT monitors can show different resolutions. The resolution can be changed as required. LCD Monitors will have Native Resolution and therefore has a fixed resolution. The best resolution will be the native resolution for that LCD monitor.

CRT
Speaking of easy on your eyes, there isn't any glare, and the flat screen means no distortion. By the way, even those expensive old-fashioned flat screen CRT monitors have some distortion. Monitor's size: Traditional monitors are similar to a TV because both of them have the CRT (Cathode Ray Tube). That is the reason for its bigger size. It therefore occupies more space at the desk. It is also heavy. However, LCD monitors have thin flat screen. Therefore occupies very less space and is lighter than the CRT monitor. LCD monitors can be fixed even on wall. Display Size: Even though the display size of a CRT monitor is calculated diagonally, the actual display size is smaller. For instance a 17" CRT monitor will actually have a display size of only 16" However, the display size of 17" LCD monitor will have 17" display size.

CRT Monitor Power Usage

Several times I had observed that my laptop battery lasts a lot longer if I turn down the brightness of the screen. That just seems such a common sense thing to do. But I never took power consumption of monitor that seriously till one day I almost burned my hands while trying to move the big bulky 19 inch CRT monitor. The back side of the monitor was really hot.

Boy, how much power does this one consume? A quick look at the manual and turns out that my old big bulky 19” monitor was consuming a whopping 120 Watts. It’s like having a big bright bulb burning right in your face. That figure was big enough for me to switch off my monitor while not working. But still I wondered, what is the exact relation between what is being showed on screen and how much power is being consumed by the monitor.

A really good EBay deal on P4400 KillAWatt by P3 International convinced me that God wants me to buy a power meter and investigate this in detail. For anyone interested in “watching your power”, this is a handy thing for about $30.

I ventured onto this study. I checked monitor power consumption for CRT (Cathode Ray Tube aka big, bulky, heavy, TV shaped, ugly, dinosaurs), as well as LCD monitors (Liquid Crystal Display aka thin , flat, light, cool cuties) . Since 17” monitors are the most common, I chose Compaq S710 in my office (which is CRT 17”) and Hundai Imagequest L70N, which is LCD 17” monitor for study and comparison.

I checked following things

• CRT monitor consumption vis-à-vis LCD monitor consumption
• Brightness settings varied 0, 50, 100
• Contrast settings varied 0, 50,100
• Screen background changed black, gray, white
• Soft power off (off using power settings of computer) and hard power off (off using switch) consumptions.

LCD and CRT Monitor Advantages and Disadvantages

LCD Monitor Advantages

· Uses Less Power. LCDs also produce less heat, which means less load on air conditioning.
· Takes up less space. LCD monitors are small, thin, and weigh less.
· Highly adjustable. Many LCD models can be rotated 90 degrees, allowing you to view websites in portrait mode. LCDs can also be mounted on the wall or on an arm.
· No flicker. LCDs don't have lines that need to be scanned like in CRTs. No flicker = a lot less eye strain.
· Less glare. Due to the material of the LCD screen, less light is reflected at the user. Same with "no flicker", this results in less eye strain.
· Brightness. LCD monitors are brighter than the traditional CRTs.
· Less distortion. Using a direct digital input from the graphics card produces cleaner 'output'. The monitor's perfect geometry means images aren't distorted, which is a boon for graphic designers and the like.
· Energy Efficient
· The scan lines and constant light barrage of a CRT tube tend to cause strain on heavy custom computer users.
· On the other hand lower intensity of LCD monitors produces less fatigue for computer users.

LCD Monitor Disadvantages

Blurry Images Outside Native Resolution
Motion Blur on Fast Moving Images
LCD’s another drawback was the lower response time when playing a video, though there has been several improvements, but there are some LCD monitors that still have lower response times. You must be aware of low response time factor of LCD monitors when purchasing it.
· Another problem of LCD monitors is color clarity. Unluckily, the PC industry has not taken some proper steps to guide and help buyers understand or compare monitors through providing listings, specifications etc.
· More expensive than CRTs. You pay for what you get; LCDs look good and are good for your eyes
· Dead pixels. When the electrical current to one or more pixels does not operate properly, one or more cells are permanently aligned, resulting in a dead pixel.
· Screen care and fragility. LCD monitors may be slim and sexy, but they're also more prone to damage and screen breakage.
· Native resolution. LCD monitors can only display information well at the resolution they were designed for. At any other resolution, image quality will suffer.
· Pixel response time. In videos and fast-paced video games, LCDs suffer from the ghosting effect.
· Viewing angles. Looking at an LCD monitor from an angle causes the image to look dimmer or even disappear completely.
· Colors. The color accuracy of an LCD monitor does not match that of a CRT monitor's.
· Now, the disadvantage was noticed the bigger is the native or fixed resolution of LCD screens. Only pixels in matrix can be displayed through an LCD monitor. It can display a lower resolution in one of two ways. Utilizing very less of the total pixels when display or through extrapolation. Extrapolation is a process through the monitor blends multiple pixels together to generate a single pixel.

CRT Monitors
Advantages:
· Color rendering is the primary advantage that CRT monitors held over LCD monitors. The depths of colors displayed and contrast ratios were much greater and better with CRT monitors than LCD monitors. While it is still true in only some cases, many series have been produced in LCD monitors such that the difference is not as great as once it was.Obviously the other benefit that CRT monitors provide over LCD screens is the ability to easily scale the various resolutions. This is dubbed to as multisync by the custom built PC industry. The screen may easily be adjusted downward to lower resolutions through adjusting the electron beam in the tube, while keeping the picture clarity intact.

• High Refresh Rates

• Color Clarity and Depth

• Multisync Capable

Disadvantages:
· The biggest disadvantages of CRT monitors are the weight and size of tubes. A same sized LCD monitor is more of 80% smaller in weight and size when compared to a CRT tube. The other bigger disadvantage is more power consumption. CRT monitor needs energy for electron beam means more consumption of power and more generation of heat than a LCD monitor.

• Very Heavy and Large

• Generate Excess Heat

• Use Large Amounts of Energy

CONCLUSION

Well, as per demand is concerned, lots of people would like to purchase LCD monitors rather than CRT monitors for their custom built PCs. There is no huge difference in the cost to consumer. Normally CRTs would only be seen sold with the rather cheap custom built PCs or by those who needs special imaging as graphics professionals.

Tips for caring eyes in front of computer

Studies have found that the majority of people who work at a computer experience some eye or vision problems, and that the level of discomfort appears to increase with the amount of computer use.

But, increased use of smaller, portable work and recreational gadgets such as Personal Digital Assistants, laptops and cell phones used for text messaging and Web access may also be contributing factors to the visual fatigue and discomfort experienced by millions, according to a leading expert.

"The unique characteristics and high visual demands of computer work and play make many individuals susceptible to the development of eye and vision-related problems," notes Dr. Jeffrey Anshel, a practicing optometrist and author of Visual Ergonomics in the Workplace. "With the proliferation of portable electronic devices such as laptops, palm pilots and video game players, it's no surprise that eye care professionals are seeing more patients who complain of ocular discomfort."

Indeed, a national survey of doctors of optometry found that more than 14 percent of their patients present with eye or vision-related symptoms resulting from computer work. Furthermore, in a survey of more than 2,000 current and former contact lens wearers, time spent in front of a computer (41 percent) was the activity most frequently mentioned as causing discomfort while they were wearing their lenses.

Staring at a computer monitor or the small screens on most devices can lead to a variety of ailments, including headaches, eyestrain, blurred vision, dry and irritated eyes, neck and/or backache and sensitivity to light.

"Eye stress and strain may be caused by a combination of individual visual problems, improper viewing habits and poor environmental conditions, such as glare, improper workstation set up, dirty screens, poor lighting and viewing angles," explains Dr. Anshel, who has helped companies and government agencies, including Mitsubishi, American Airlines, 3M and the Department of Labor address the high stress area of vision demands in relation to working with computer monitors.

"Uncorrected or under-corrected vision problems can be major contributing factors to computer related eye stress, affecting visual performance and comfort," cautions Dr. Anshel.

"The good news is that many potential eye and/or vision problems can be reduced or eliminated by appropriate adjustment and placement of computer monitors, lighting control, good preventive vision care habits and regular professional eye care." Dr. Anshel offers the following advice to help prevent or reduce the development of vision-related problems.

For additional tips, take the "Eye Q's and Views" interactive quiz at http://www.computerquiz.jnjvision.com.

-- REDUCE GLARE - Extraneous light, or glare, is the greatest source of eyestrain for computer users. No matter where your computer is relative to a window, adjustable shades, curtains or blinds should be used to effectively control light levels throughout the day. Avoid facing an un-shaded window since the difference in brightness between the screen and the area behind it may be cause eye stress and discomfort. Consider using an anti-glare screen to reduce reflections.

-- CHECK YOUR CONTACTS - When working at a computer, people spend a lot of time concentrating and blink less frequently - about three times less than normally, according to studies. "Computer work is particularly stressful for contact lens wearers," says Dr. Anshel. "Long non-blinking phases may cause the surface of contact lenses to dry out, which can lead to discomfort and a loss of visual clarity." He recommends talking to an eye care professional about ACUVUE® OASYS™ with HYDRACLEAR™ Plus. In a clinical study with 335 contact lens wearers, nine in 10 (89 percent) patients wearing ACUVUE® OASYS™ said that their eyes felt comfortable, even when watching TV or using a computer for a long time.

-- ADJUST YOUR MONITOR - Ideal monitor placement is dependent on several factors including an individual's physical make-up and visual capabilities, work tasks and other workstation design elements. For maximum eye comfort, Dr. Anshel recommends placing the center of the screen five to nine inches below your horizontal line of sight. "You should be looking just over the top of the monitor in your straight-ahead gaze," he says.

-- TAKE A BREAK - "Our eyes were not made to see at a close distance for hours at a time without a break," says Dr. Anshel. A preventive approach to reducing visual stress includes occasionally looking away from the screen of your computer, PDA or portable game player. Dr. Anshel recommends the 20/20/20 rule. "Take a 20-second break every 20 minutes. Focus your eyes on points at least 20 feet from your terminal. Keep your eyes moving while looking at objects at various distances," he says.
-- CONSULT YOUR EYE CARE PROFESSIONAL - The American Optometric Association highly suggests yearly eye exams to ensure ocular health. For individuals whose jobs may require extensive time in front of a monitor, Dr. Anshel suggests a comprehensive eye examination soon after beginning computer work and periodically thereafter. "If, at any time, you experience any vision problems or discomfort, talk to your eye care professional," he adds.

Tips To Avoiding the Fatigue Eyes while we working in front of Computer all day

Some of us would have the habit to work for long in front of a PC monitor, either to work or doing other things like playing games and browsing. As a result the effects of eye fatigue and dizziness head was unavoidable.
While many consider this fact not entirely true, but in reality it is still affecting the health of our eyes. The effect we sometimes a little difficult to focus the object of view, and so forth. This of course caused a radiation monitor for too long when we work.

Here are some tips to avoid eye fatigue in front of the computer:
1. Keep your distance from the monitor
Being too close to the monitor is a bit dangerous for our eyes. We should maintain visibility into the monitor.
2. Get rid of CRT, Switch to LCD
Monitor tube (CRT) does give a worse effect than the LCD, in addition to the energy required is also greater. Try replacing CRT monitors with LCD.
But the price of LCD monitors are more expensive than CRT. It's good we buy anti-radiation filters. This is the solution to reduce the pain from the eyes linger in front of the monitor, but with a cheap price.
3. Set the monitor settings
Some monitors are now many provide pre-set display modes, to allow users to change the display settings. Pre-set these settings to give different levels brightnes, to adjust the conditions of use of the monitor.
For example settings such as, 'text' or 'internet' will feel much cooler in the eyes, when we use for typing or browsing. Setting 'game' or 'movie' will look much brighter when used.
4. Use anti-radiation glasses
Although it costs a relatively more expensive, but it's good to have enough money, we buy anti-radiation glasses. In addition you can take them wherever we work, these glasses are not only useful when we work in front of the monitor, but also protect the eye from the car light, radiation, TV, and so forth.
In fact the anti-radiation coating on the glasses, very useful for our eyes. Because the layer automatically reduces the effects of pain in the eyes of radiation due to excessive light.
5. Rest my eyes for a moment, on a regular basis
The easiest way to avoid eye fatigue due to radiation monitors are mengistirahatkannya periodically. Try to rest eyes for about 5 minutes every hour. We can use it to take 5 minutes see the sights, washing face and so forth. The important thing away from the monitor.

How Does Touchscreen work?

How Does a Touchscreen Work???

 

A basic touchscreen has three main components: a touch sensor, a controller, and a software driver. The touchscreen is an input device, so it needs to be combined with a display and a PC or other device to make a complete touch input system.
1. Touch Sensor
A touch screen sensor is a clear glass panel with a touch responsive surface. The touch sensor/panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the video screen. There are several different touch sensor technologies on the market today, each using a different method to detect touch input. The sensor generally has an electrical current or signal going through it and touching the screen causes a voltage or signal change. This voltage change is used to determine the location of the touch to the screen.
2. Controller
The controller is a small PC card that connects between the touch sensor and the PC. It takes information from the touch sensor and translates it into information that PC can understand. The controller is usually installed inside the monitor for integrated monitors or it is housed in a plastic case for external touch add-ons/overlays. The controller determines what type of interface/connection you will need on the PC. Integrated touch monitors will have an extra cable connection on the back for the touchscreen. Controllers are available that can connect to a Serial/COM port (PC) or to a USB port (PC or Macintosh). Specialized controllers are also available that work with DVD players and other devices.

3. Software Driver
The driver is a software update for the PC system that allows the touchscreen and computer to work together. It tells the computer's operating system how to interpret the touch event information that is sent from the controller. Most touch screen drivers today are a mouse-emulation type driver. This makes touching the screen the same as clicking your mouse at the same location on the screen. This allows the touchscreen to work with existing software and allows new applications to be developed without the need for touchscreen specific programming. Some equipment such as thin client terminals, DVD players, and specialized computer systems either do not use software drivers or they have their own built-in touch screen driver.
Virtual Painter: Touch Screen Interface

Touchscreens Add-ons and Integrated Touchscreen Monitors
We offer two main types of touchscreen products, touchscreen add-ons and integrated touchscreen monitors. Touchscreen add-ons are touchscreen panels that hang over an existing computer monitor. Integrated touchscreen monitors are computer displays that have the touchscreen built-in. Both product types work in the same way, basically as an input device like a mouse or trackpad.

Touchscreens As Input Device
All of the touchscreens that we offer basically work like a mouse. Once the software driver for the touchscreen is installed, the touchscreen emulates mouse functions. Touching the screen is basically the same as clicking your mouse at the same point at the screen. When you touch the touchscreen, the mouse cursor will move to that point and make a mouse click. You can tap the screen twice to perform a double-click, and you can also drag your finger across the touchscreen to perform drag-and-drops. The touchscreens will normally emulate left mouse clicks. Through software, you can also switch the touchscreen to perform right mouse clicks

How The Computer Monitor / Televison Works

Most desktop displays use cathode ray tube (CRT) or liquid crystal display (LCD) technology, while nearly all portable computing devices such as laptops incorporate LCD technology. Because of their slimmer design and lower energy consumption, monitors using LCD technology (also called flat panel or flat screen displays) are replacing the venerable CRT on most desktops.
Now lets take a look on how cathode ray tube (CRT) works.

-The CRT Monitor that is most likely on your desktop is a cousin of your TV set. Of course they have come a long way since the TV as far as resolution is concerned offering 800X600 or better. Now you may think well why haven't TV's moved up to a better resolution if a computer has such good resolution? TV's are restricted to 525X700 and defined by NTSC (North American Television Standards Commission), surprised? Seems as if everything is made a standard and some bogus organization will make sure they make a buck on it. Well, now how does your monitor make the picture on the screen and do it fast?

In CRT Monitors, the beginning process of the monitor starts with a electron gun. This gun has the job of spraying a focused beam on the glass of the CRT tube, the tube is also in a vacuum. The inside of the glass tube that you are looking at is lined with a phosphorescent material that glows a specific color when excited by the electron gun. Now when the electron gun is firing it is usually through a aperture grill or mask. This mask insures the electron's from the gun hit precise points and make the picture sharper and look great. Now we know when the gun hits the material on the glass it will turn a certain color. We are working with (RGB) red, blue, and green colors that make up individual pixels. If the electron gun hits one pixel with just the right frequency of electrons we will have say a red pixel, little more frequency of electrons we move into a blue and so on. Making all these pixels match up into a image is a big task. So you are probably thinking how does this electron gun go across the screen and does it move this much?

-The electron gun has to update these pixels as much as 70 times a second. This has to be done to keep the phosphors lit. They do burn out if not updated and refreshed often. We need a faster gun then Jesse James for this action. Now, the process of updating the screen is called refresh. You probably have heard that term a few times and is in Hertz on a computer such as 75Hz. This means the monitor refreshes 75 times a second. Remember MHz in CPU's which can calculate information 500 million times a second? Not to slow is it.. Now when the monitor has to refresh a row of pixels we start on the left top side of screen. This is done from the left then goes to the right side, only to be turned off and start all over again at the next row. Now when you have a 800X600 resolution the electron ray gun has to spray 800 pixels per row and do 600 rows. Now do this 75 times a second or more. Kind cool huh? So does this gun just move back and forth from the back of the computer to paint our screen? No, usually for higher rates such as 75Hz and upwards magnetic fields are used to guide the electrons to there pixels more precisely.

Resolution refers to the number of individual dots of color, known as pixels, contained on a display. Resolution is expressed by identifying the number of pixels on the horizontal axis (rows) and the number on the vertical axis (columns), such as 800x600. Resolution is affected by a number of factors, including the size of the screen.
pixel is the smallest element of an image.
As monitor sizes have increased over the years, display standards and resolutions have changed. In addition, some manufacturers offer widescreen displays designed for viewing DVD movies.
How the LCD works

LCD monitor

We learned in school that there are three common states of matter: solid, liquid or gaseous. Solids act the way they do because their molecules always maintain their orientation and stay in the same position with respect to one another. The molecules in liquids are just the opposite: They can change their orientation and move anywhere in the liquid. But there are some substances that can exist in an odd state that is sort of like a liquid and sort of like a solid. When they are in this state, their molecules tend to maintain their orientation, like the molecules in a solid, but also move around to different positions, like the molecules in a liquid. This means that liquid crystals are neither a solid nor a liquid. That's how they ended up with their seemingly contradictory name.

So, do liquid crystals act like solids or liquids or something else? It turns out that liquid crystals are closer to a liquid state than a solid. It takes a fair amount of heat to change a suitable substance from a solid into a liquid crystal, and it only takes a little more heat to turn that same liquid crystal into a real liquid. This explains why liquid crystals are very sensitive to temperature and why they are used to make thermometers and mood rings. It also explains why a laptop computer display may act funny in cold weather or during a hot day at the beach.

How To fix or repair A Computer Monitor Work that fails to start / turn ON

How to Repair/Fix a Computer Monitor That Fails to Start/Turn On

 

If you turn on your computer but it shows an empty screen with no power or display, there's definitely something wrong going on. You don't have to fret, though. This problem can be solved easily depending on what has caused it. There are several reasons why a PC monitor suddenly refuses to turn on.
The first thing to do in this situation is to check the cables. Most problems with computer screens are related to loose cables. Check if the VGA cables are connected securely to your PC monitor. If there are loose screws, the cables may not be held in place correctly, which leads to monitor problems. Tightening up the screws may help in solving the problem. Additionally, check if the UPS has short circuited. Plug the monitor to a wall socket and determine if you need to replace the surge protector.

Sometimes, the problem might be the monitor itself. If you have a spare monitor or other computers at home, you can try using a functioning monitor to replace your monitor and see if it works. On the other hand, if it doesn't work, you may have to replace the monitor since the problem could be the computer screen. If it does work, the problem may be related to the video card. Monitor failure can be caused by a loose video card. You can check if the video card is seated properly by opening up the case. Make sure that your computer is turned off and unplugged from the power source. Try pulling out the video card and inserting it back securely. Check if this solves your problem. If the loose card has caused the problem, your monitor should be able to power on and function normally again. If the video card doesn't work properly anymore, you may have to replace it. Ask help from an expert friend.

Whatever happens, never open the monitor and tinker with it to avoid risks. It can be quite dangerous since it is made up of intricate parts that even some expert technicians do not want to disassemble. If worse comes to worst, you should just opt to change your monitor instead of trying to fix it inside. If your PC is still under warranty, you can also send it back to the manufacturer so that computer technicians can check and fix it. However, it can be a very long and tedious process. Another alternative is to hire a professional computer specialist to check your computer and repair the problem.

LCD Display Powered By Ambient Light

Samsung Displays Touchscreen Transparent LCD Display Powered by Ambient Light

Samsung made waves recently by displaying their newest creation, a transparent LCD display. Well, they have tweaked their existing LCD technology in order to make it more energy efficient. Now the transparent LCD display is energy efficient enough to be powered by ambient light.
CeBIT 2011 was fortunate enough to see a working demo of the technology that had a viewable size of 46 inches and supported full 1080p HD resolution. The device also provided a full ten finger touchscreen surface.
The panel uses a vertical alignment display mode and is an improvement over the see-through LCD panel that Samsung showed off at the SID 2010 in Seattle in May of last year. A spokeswoman for Samsung Electronics has been quoted as saying that a fridge freezer may be a potential application.
The spokeswoman did decline to say, however, whether or not the innovative solar panel will be applied to other, similar products. Be that as it may, the simple fact that Samsung was able to cut down power consumption on such a level that the device can be powered by ambient light is an impressive feat in itself.

It has also been said that Samsung will be working on bigger sized panels. The company's biggest panel on the market currently measures 65 inches.
Other details surrounding the panel, like power consumption and the position of the backlight unit, have yet to be revealed though a lot of people are speculating that the backlight unit will be located on the top of the panel. There were a few things, like a few problems with the touchscreen not working, that suggest that the technology is not quite ready yet.
A few interesting things to look for when this device does hit consumers' homes is how it will stack up against your more traditional displays in terms of color reproduction, refresh rates, price etc... Another interesting idea was to combine these transparent LCD displays in order to create glasses-free 3D TVs.
Samsung showed a demo of its largest OLED display, a 19-incher, earlier this year at CES 2011. It is, however, a little unlikely that this production prototype will come to be anything more than a showcase for the next few years.

Tips To Make Cheap And Best Personal Computer or PC

Everyone who owns a computer knows how fast the technology gets outdated in Computer world. A brand new hardware which you buy today might be outdated in 10 days. Now, we just can’t keep on upgrading the hardware always so there comes a point when a user is looking for a cheap & efficient computer system with the ability to upgrade it later as required & having the best value for money. If you don’t play games or play games casually only, then this PC will easily last for 4 years without upgrading anything in it. Even if you play games then small updates will do. you might pay a bit high for the PC but then you will not need to pay a penny on it.

Now, you can go in the market & buy the best product available for your money but is it balanced? Remember, a 80% balanced PC will work better then a 100% high end component based PC as it is more efficient & there are very few flaws. I came across a configuration which I think fits this balanced & efficient PC configuration perfectly with a lot of room to upgrade as required.

CPU & Motherboard = AMD Athlon 64 X2 5000+ AM2 with Gigabyte GA-MA78GM-S2H. AMD has recently released the 780G chipset which by far is the best Value for Money chipset out there I have seen in a long time & with the Gigabyte motherboard, you get lots of features for such a low price. The feature list of this motherboard is quite long & it has everything you will ever want in a PC. When combined with the Athlon64 CPU, this machine has more then enough power to do anything you throw at it for a really low price.

Although AMD in my opinion is better then Intel when it comes to Value for Money, but if you still want to go with Intel Setup then simply buy Intel Core 2 Duo E4500 along with Asus P5E-VM HDMI. This motherboard has similar features to the AMD 780G chipset based Gigabyte motherboard sans DirectX 10 based onboard graphics. Rest all features are almost similar.

CPU Fan = The stock CPU Fan should be good enough but if you want to further reduce the noise of your computer then you can have a look at Cooler Master Gemini S CPU cooler.

Memory = RAM is relatively cheap these days. It makes perfect sense to for 2X1GB DDR2 800 MHz RAM, If you are not into overclocking then you can buy Corsair Value Select RAM for as low as Rs. 2,000 in the market. You are advised to upgrade to 2X2 GB DDR2 800 MHz RAM after about 1 or 2 years when the prices further reduce.

Cabinet & SMPS = Zebronics Cube is something I would recommend for such a PC. It is small, easy to carry & move around, gives enough room for expansion as required. This cabinet comes with a basic 400W SMPS but I would recommend to change it to Cooler Master Extreme power 500W for Rs 2,200. This will provide adequate electricity for the components.

Hard Disk = There is no limit and it depends completely on your requirements. however, as a starting point I would recommend Western Digital SATA2 WD3200AAKS Hard disk with 16 MB Buffer & 320 GB HD space. If you need more space then buy an external HD. If you can pay a it more then look for Western Digital 500GB GreenPower Hard disk. This is a RoHC compliant hard disk & required less power & electricity compared to the above mentioned 320 GB hard disk at a slight price premium but it is worth it as you will save more in electricity bills.

Optical Drive = There are many optical drives in the market right now but one Drive which is enough for needs would be Samsung SH-S203D DVD Writer at Rs 1,200.

Audio & Video = The Gigabyte motherboard already comes with a more then decent onboard audio & video configuration. The Onboard 7.1 channel Realtek ALC889A HD Audio Codec should suffice for all your HTPC needs & the onboard Radeon HD 3400 class graphics should take care of all your non-gaming needs to run the OS. The onboard graphics chip comes with UVD 2.0 which means automatic decoding of HD & VC-1 Content. If you want to upgrade then look no further then a Creative X-Fi Xtreme Audio Sound Card for about Rs 4,500 & Sapphire Radeon HD 3850 with 512 MB DDR3 RAM for about 11k. However a separate graphics card & sound card will not be needed as this PC is not meant for serious gaming.

TV Tuner Card = Buy it if you need it else leave it. I would recommend Leadtek Winfast TV2000XP Global Media Center with my eyes closed as this TV Tuner is by far the best analog TV Tuner card I have seen. It is compatible with Windows Media Center & even comes with a Media Center Remote. If you can find the PCI Express X1 based WinFast PxTV1200 Media Center Edition then buy that instead to use that idle PCI Express X1 slot to some good use.

Speakers & Headphones = This is a completely personal choice & I would advice you to go to the market & check yourself after listening to some available models.

If you are looking for headphones then look for Philips HiFi SHP-8900 headphones for Rs 3,500. Not only they look good, but for a headphone of Rs 3,500 they sound astonishingly good. It comes with gold plated 4 meter long OFC cable which is long enough to take it to to the couch too.

For speakers, although you should check yourself in the market but I would say as a starting point look for Creative Gigaworks T20 or Creative I-Trigue T3000 for Stereo Sound.

Webcam = Buy it if you need it. These days webcams start for as low as Rs 500 in the market. Considering the state of Indian broadband, a Microsoft LiveCam VX-1000 should suffice or Frontek Webcam which are surprisingly good for the price at Rs 500.

Keyboard & Mouse = Again, this is a personal preference. Look yourself to judge which keyboard & mouse you find comfortable with your hands & posture. Since this Computer is meant to be a life style PC, better go for Microsoft Wireless Laser Desktop 7000 set if your budget allows it.

Monitor = LCD Monitors are dirt cheap now so it makes prefect sense to invest in a LCD Monitor instead of a CRT now as monitors easily last for many years & is generally the last hardware component to upgrade. Since this is the HD Era it makes sense to buy a HD certified LCD Monitor such as LG L206WTQ for Rs 10,500. This monitor is 20″ with TN Based panel & HDCP compliancy. You can easily upgrade to a Blu-ray Drive later & still enjoy all your HD Movies as Blu-Ray requires a monitor with HDCP connection. It has a native resolution of 1650X1080 pixels which is more then enough for whatever you want to throw at it, even 720p HD Videos play flawless on this monitor as 1080p will look different from 720p only when seen on a 32″ or higher LCD Display. You can also connect your gaming console such as XBOX 360 or Playstation 3 to this monitor to play games on a wide screen LCD with real HD resolution.

Operating System = With all this perfectly balanced hardware, it would be a shame to use Windows XP which will severely hinder the feature & hardware power of this Machine. On the other hand, 64bit Windows Vista Home Premium for Rs 4.200 will compliment this hardware completely out of the box. It’s more like the OS & this machine are made to complement one another. Once installed & configured for which you can have a look at my article “Using Windows Vista : The MVP Way” & your setup will be like Set it & forget it. Just start the system, work on it & do what ever you want.

If you are into Linux, even then this hardware setup is perfectly suited as the drivers are easily available & since you are into Linux, chances are you are not afraid or tinkering around with the OS. Linux Mint is something I would recommend to start with in this case. You might loose some features such as Blu-ray playback etc with Linux but there are always other ways.

I have written some prices which I personally know, however you can have a look at Lynx India or TheITwares for better idea of approximate prices.

This PC is not supposed to be a high end PC, it is supposed to be a small, silent & “Does your work without hassle” PC.

The Benefit for Flat Computer Monitors

The benefits of a flat computer monitor has rocketed their popularity and sales. Look in any electronics store down the high street or online and you'll find nothing but flat screen monitors. For graphics and web designers this has been a major breakthrough and is helping shape the future of graphics design.
More colors and more pixels allow for better accuracy and finer detail. Images are much more lifelike and many flat computer monitors can reproduce accurate colors compared to print. Obviously, this is very handy for graphics designers since they are displayed an image that is as close to the final product.

This is not always the case though since some LCD monitors can change color and differ in contrast and saturation. If you use your computer predominately for web or print design it is worthwhile seeing the real thing in action at an electronics outlet.
Flat computer monitors generally come in either matte or glossy. There are many a disagreement to which is better, but at the end of the day it's really down to personal preference. Glossy monitors are more reflective and may be difficult to see when there is a strong light source behind you. They tend be clearer and more vibrant than the matter variety.
Matte screens are less affected by glare and usually easier on the eyes. One drawback is that they can be a little duller and images may not look as lifelike as they do on a glossy screen. Before deciding on which one to go for you should consider what you will be using it for and more importantly, where.

People buying a flat computer monitor for personal and not work have more freedom to move their monitor, so picking a glossy monitor over a glossy shouldn't be a problem. Many individuals prefer glossy since it makes viewing photos, watching movies and gaming a lot crisper and much more vivid.
Flat screen monitors generally go up to about 32 inches which should be sufficient for any purpose. There's nothing to stop you however from rigging a 52 inch flat screen TV to your computer though. For dual setups having two 24 inch screens is a good size. As with most things the bigger you go the more expensive it is. For an average size flat screen monitor you're looking around the $200 mark. Larger monitors can fetch up to $2000 and beyond.

Flat LCD Monitors

Flat Computer Monitor

 

The benefits of a flat computer monitor has rocketed their popularity and sales. Look in any electronics store down the high street or online and you'll find nothing but flat screen monitors. For graphics and web designers this has been a major breakthrough and is helping shape the future of graphics design.
More colors and more pixels allow for better accuracy and finer detail. Images are much more lifelike and many flat computer monitors can reproduce accurate colors compared to print. Obviously, this is very handy for graphics designers since they are displayed an image that is as close to the final product.
This is not always the case though since some LCD monitors can change color and differ in contrast and saturation. If you use your computer predominately for web or print design it is worthwhile seeing the real thing in action at an electronics outlet.
Flat computer monitors generally come in either matte or glossy. There are many a disagreement to which is better, but at the end of the day it's really down to personal preference. Glossy monitors are more reflective and may be difficult to see when there is a strong light source behind you. They tend be clearer and more vibrant than the matter variety.
Matte screens are less affected by glare and usually easier on the eyes. One drawback is that they can be a little duller and images may not look as lifelike as they do on a glossy screen. Before deciding on which one to go for you should consider what you will be using it for and more importantly, where.

People buying a flat computer monitor for personal and not work have more freedom to move their monitor, so picking a glossy monitor over a glossy shouldn't be a problem. Many individuals prefer glossy since it makes viewing photos, watching movies and gaming a lot crisper and much more vivid.
Flat screen monitors generally go up to about 32 inches which should be sufficient for any purpose. There's nothing to stop you however from rigging a 52 inch flat screen TV to your computer though. For dual setups having two 24 inch screens is a good size. As with most things the bigger you go the more expensive it is. For an average size flat screen monitor you're looking around the $200 mark. Larger monitors can fetch up to $2000 and beyond.

Choosing Flat Computer Monitors

Choosing Flat Computer Monitors

 

Choosing flat computer monitors can be a rather daunting task these days. There are now so many brands, models and features to consider when it comes to buying new monitors it can make your head spin in a second.
To avoid this anxiety there are a few basic things you need to consider when choosing your new screen.
First of all is budget, how much have you got to spend ? Do you want the brand new latest and greatest or will a second hand older model do the trick. Flat screen monitors are generally most people’s choice now as they are a lot sleeker and take up a lot less space than traditional flat computer monitors.
Next of all is size. Now most people want the biggest screen that they can afford but going big is not necessarily always better. The bigger the screen the bigger the price tag is a common rule of thumb when it comes to flat computer monitors. Also big monitors take up a big chunk of space on your desk as well leaving you a lot less room to do your work in.
But probably the biggest issue here is if you are used to a normal sized flat computer monitor and the upgrade to the big daddy it can be a little too much for your senses to take in making it harder and not easier to recognize what is happening on the screen.

Finally comes format and there are two types of format to consider here. Conventional format which is 4:3 or Widescreen Format which is 16:9. This actually comes down to personal preference, many buyers are partial to the older and more square 4:3 format as it just feels better to them.
Others however, especially those who will be using their flat computer monitors for work purposes, will prefer the open feeling of the 16:9 widescreen. The 16:9 widescreen has just a little more room for opening multiple programs and it makes it a lot easier to see at a glance as it’s not so confined.
Price is king when purchasing flat computer monitors. Most monitors are pretty much created equal these days and quite often I have found that many different brands of monitors are actually identical and even made in the exact same factory so price is the biggie here.
Here is a review of what in our opinion are the four best options on the market today for all price brackets.
The 4 flat computer monitors covered below are nothing short of outstanding. It has been nearly a whole year since our last test and review session and this 2010 stock is the best we have seen yet.

Starting from the top down they are…
The Dell Ultra Sharp U2711
$1050 will land you this mother of all other flat computer monitors. It’s use for playing games, dvd’s, and photos is well justified due to it’s whopping 2560 x 1440 screen resolution.
Colors have never looked like this before when viewed on a monitor. Even with it’s hefty price tag this is the rolls Royce of flat computer monitors. If you can afford it, own it !
Samsung Sync Master XL2370
This is a lower priced well designed unit in every aspect combined with across the board mid range performance. Probably the most striking factor with these flat computer monitors is just how thin and how little they weigh. The Samsung Sync Master XL2370 is very stylish and very well priced in the market.
Dell Ultra Sharp 2408WFP
This little 24-inch demon of a display delivers across the whole performance spectrum. It is truly brilliant for entertainment and is currently the choice for gamers the world over.
And finally
Dell SP2309W
Three things here folks. Low price, loads of cool features and top level performance that you would usually only expect from the $800 and up flat computer monitors. For the general household out there that wants the best performing monitor for the lowest possible price, this is it baby.

Tips To Buy Cheap LCD Monitors

Monitor "LCD cheap" is a stylish solution to get a computer but sparingly. Excess LCD monitor power consumption is low and does not take much space. Her presence began to shift the position of the monitor tube (CRT).
The price of LCD monitors are still rising, but the increasing number of LCD monitors are manufactured to make the price go down relatively cheaper. And this is good news for those who want to replace the tube monitors with LCD monitors.

The LCD monitor is already a lot cheaper on the market. However, there is no harm if we know what the pros and cons. Here we discussed together.
1. LCD monitors have a fixed native resolution. This means that the monitor will work well if used in the default resolution. For example, an LCD monitor that has 1024x768 resolution, will work fine in that resolution. Therefore you must be smart in choosing an LCD monitor according to the resolution you need. Most low-cost LCD size 14 "is not good working in 1024x768 resolution.
2. Performance of the LCD monitor is measured in milliseconds. LCD monitor that has a slow speed in displaying image from CPU, will be visible when you play 3D games. Blurred images will look when you run 3D games on the LCD monitor is slow. The possibility of low-cost LCD monitors do not have the speed as fast as LCDs are a bit expensive.
Therefore, the LCD monitor to be adjusted to our needs. And to say lucky people who get cheap LCD monitors at once needs are met.

Type and Definition of LCD Monitors

With manufacturing improving, LCD panel sizes continue to get larger all while prices keep dropping. Retailers and manufacturers throw around a lot of numbers and terms to describe their products. So, how does one know what all these mean? This article looks to cover the basics so one can make an informed decision when buying an LCD monitor.

SCREEN SIZE

The screen size is the measurement of the displayable area of the screen from the lower corner to the opposite upper corner of the display. LCD's typically gave their actual measurements but they are now rounding those numbers. Be sure to find the real dimensions typically referred to as the actual screen size the whenever looking at a LCD.

ASPECT RATIO

The aspect ratio refers to the number of horizontal pixels to vertical pixels in a display. Traditional displays used a 4:3 aspect ratio. Most new widescreen monitors use either a 16:10 or 16:9 aspect ratio. The 16:9 is the ratio typically used for HDTVs. Now a new breed of ultra wide monitors is coming to market. These have a near 2:1 width to high measurements.

MATIVE RESOLUTIONS

All LCD screens can actually display only a single given resolution referred to as the native resolution. This is the physical number of horizontal and vertical pixels that make up the LCD matrix of the display. Setting a computer display to a resolution lower than this resolution will either cause extrapolation. This extrapolation attempts to blend multiple pixels together to produce a similar image to what you would see if the monitor were to display it at the given resolution but it can result in fuzzy images.

Here are some of the common native resolutions found in LCD monitors:

• 17-19": 1280x1024 (SXGA)
• 20"+: 1600x1200 (UXGA)
• 17" (Widescreen): 1280x800 (WXGA)
• 19" (Widescreen): 1440x900 (WXGA+)
• 22" (Widescreen): 1680x1050 (WSXGA+)
• 23.6" (Widescreen): 1920x1080 (WUXGA)
• 23" (Ultra-Widescreen): 2048x1152 (QWXGA)
• 24" (Widescreen): 1920x1200 (WUXGA)
• 30" (Widescreen): 2560x1600

CONTRAST RATIO

Contrast ratios are a big marketing tool by the manufacturers and one that is not easy for consumers to grasp. Essentially, this is the measurement of the difference in brightness from the darkest to brightest portion on the screen. The problem is that this measurement will vary throughout the screen. This is due to the slight variations in the lighting behind the panel. Manufacturers will use the highest contrast ratio they can find on a screen, so it is somewhat deceptive. Basically a higher contrast ratio will mean that the screen will tend to have deeper blacks and brighter whites.

COLOR GAMUT

Each LCD panel will vary slightly in how well they can reproduce color. When an LCD is being used for tasks that require a high level of color accuracy, it is important to find out what the panel's color gamut is. This is a description that lets you know how wide a range of color the screen can display. The larger the percentage of NTSC, the greater level of color a monitor can display. It is somewhat complex and best described in my article on Color Gamuts.

RESPONSE TIMES

In order to achieve the color on a pixel in an LCD panel, a current is applied to the crystals at that pixel to change the state of the crystals. Response times refer to the amount of time it takes for the crystals in the panel to move from an on to off state. A rising response time refers to the amount of time it takes to turn on the crystals and the falling time is the amount of time it takes for the crystals to move from an on to off state. Rising times tend to be very fast on LCDs, but the falling time tends to be much slower. This tends to cause a slight blurring effect on bright moving images on black backgrounds. The lower the response time, the less of a blurring effect there will be on the screen. Most response times now refer to a gray to gray rating that generates a lower time than the traditional full on to off state response times.

VIEWING ANGLES

LCD's produce their image by having a film that when a current runs through the pixel, it turns on that shade of color. The problem with the LCD film is that this color can only be accurately represented when viewed straight on. The further away from a perpendicular viewing angle, the color will tend to wash out. The LCD monitors are generally rated for their visible viewing angle for both horizontal and vertical. This is rated in degrees and is the arc of a semicircle whose center is at the perpendicular to the screen. A theoretical viewing angle of 180 degrees would mean that it is fully visible from any angle in front of the screen. A higher viewing angle is preferred over a lower angle unless you happen to want some security with your screen.

CONNECTORS

Most LCD panels have an analog and a digital connector on them. The analog connector is the VGA or DSUB-15. The common digital interface is the DVI connector. This is a digital interface that is supposed to allow for a cleaner and brighter picture compared to standard VGA connectors. HDMI and DisplayPort are two other digital interfaces that are becoming common. Check to see what type of connector your video card can use before buying a monitor to ensure you get a compatible monitor. Some monitors may also come with home theater connectors including component, composite and S-video.

STANDS

Many people don't consider the stand when purchasing a monitor but it can make a huge difference. There are typically four different types of adjustment: height, tilt, swivel and pivot. Many less expensive monitors only feature the tilt adjustment. Height, tilt and swivel are generally the critical types of adjustments allowing for the greatest flexibility when using the monitor in the most ergonmoic fashion.

3 Ways To Tweak Your PC Monitor For High Quality Display & Performance

1. Adjust your monitor's brightness & contrast either manually or automatically. Use a high-quality video source with a good color range as a reference for your settings.

2. Upgrade your graphic card drivers to the latest features supported by your card. Use a screen calibration software to optimize your monitor further. (Just as you calibrate your plasma TV, even a LCD monitor works best when calibrated to the ambiance of your home or office)

3. Use a good-quality cable between your monitor & CPU. Check the connectors for any bent pins and replace them in time to maintain hardware integrity.
