Q. There are many different types of Moniters in the market-CRT, TFT, LCD etc. I would like to know is there any difference in display,? Which is the best for the eye to view without much strain ?
A. A TFT monitor uses thin-film transistor technology for the ultimate LCD or liquid crystal display. LCD monitors, also called flat panel displays, are replacing the old style cathode ray tubes (CRTs) as the display of choice. Nearly all LCD monitors today use TFT technology.
The benefit of a TFT monitor is a separate, tiny transistor for each pixel on the display. Because each transistor is so small, the amount of charge needed to control it is also small. This allows for very fast re-drawing of the display, as the image is re-painted or refreshed several times per second.
Prior to TFT, passive matrix LCD displays could not keep up with fast moving images. A mouse dragged across the screen, for example, from point A to point B, would disappear between the two points. A TFT monitor can track the mouse, resulting in a display that can be used for video, gaming and all forms of multimedia.
A typical 17-inch TFT monitor has about 1.3 million pixels and 1.3 million transistors. That leaves a significant chance for a malfunctioning transistor or two on the panel. Upon delivery, a TFT monitor can have "dead pixels" for this reason. A dead pixel is a pixel whose transistor has failed, thereby creating no display image. On a solid black background, dead pixels will stand out as tiny dots of red, white or blue. Most manufacturers will not replace a TFT monitor that has less than 11 dead pixels. Often, a TFT monitor won't have any dead pixels —- always the hope for any buyer, though dead pixels are not noticeable unless located in a critical position on the screen.
There are only a handful of TFT factories that turn out panels for all brands of TFT monitors. Since there is a given failure rate -- considering how many transistors are on each panel -- only so many of the displays come out bearing no dead pixels, while a certain percentage bear an acceptable number of dead pixels and other panels are unusable. The panels that bear some dead pixels are often sold to be used in discount models. If looking for a TFT monitor, it is a good idea to read feedback provided by buyers at popular online retail sites. By scanning the reviews for several brands, it is easy to get a feel for which models have consistently good panels that rarely bear dead pixels.
A TFT monitor delivers crisp text, vibrant color and an improved response time for multimedia applications. If interested in gaming, video editing or other multimedia applications, look for a TFT monitor with a response rate of 16ms or less. The DVI (digital visual/video interface) is also a good feature to get, as it will make the monitor more future-proof.
i broke my sony camera, should i invest in a new sony digital camera or buy a canon?
Q. i've heard canon brand is better than sony, but since i already have the battery, charger and memory card i was thinking about getting another sony..
so do i buy a Sony camera or go for a Canon?????
what's your advice?
A. Tough choice, but think the Canon below would really be the best.
Just saw this camera at Best Buy and think it is a great camera and a best buy. It has an optical viewfinder and uses NiMH rechargeable batteries. Please read as much of the following as you can for other information and help with choosing a camera.
Canon A590IS $134.99 at Best Buy or $116.30 at Amazon.com

Camera reports batteries low, but is it low charge or bad electrical contacts? Overcharging can ruin good batteries! The secret to making digital cameras work better is having good electrical contacts between batteries and camera.
Digital cameras require lots of power. Bad electrical contacts can cause lots of problems so battery and camera contacts must be cleaned properly. Batteries may be fully charged, but will be viewed as low if contacts are not really good. The LCD screen is a low steady load, but when lens extension, optical zoom, focus, and flash charging are added in the capture mode; the load is very heavy. Bad contacts make cameras do strange things like making bad pictures or shutting off with the lens out.
CAUTION Do not overcharge! Batteries can be severely damaged. Use an automatic two or more hour Energizer Compact smart charger with safety timer, temperature monitor, and trickle charge technology ($9.76) at Walmart. For longer life, use Duracell 2000mAh batteries and a full cycle charge monthly. To preserve battery charge, use the view finder and not the LCD screen when possible.
There are so many cameras out there it is difficult to say which is best, but digital is definitely the way to go. The second source link will be very helpful as it list most of the cameras out there with prices.
What gives a camera its picture quality? The following information should help you know what to look for in a camera.
The short answer is that it is mostly the skill of the photographer that produces high quality pictures. The lens and camera are very important, but the ability to set the scene, adjust the cameras settings, and hold the camera very still or use a tripod with auto or remote shutter actuation when required is what gets the great pictures.
Many of the new cameras come with only an LCD screen. Would suggest that you find one that also has an optical view finder because the LCD screen is almost impossible to see in bright sun.
Higher mega pixels may not really be the best thing to look for. It is more expensive, takes longer to process, and may not be needed unless you are making a really large picture or blowing up a small part of a picture. Maximum print size for a 3 mega pixel setting is 8 x 10 inches.

The information about my camera is just to show that you don't need the biggest and best. Just know how to use the one you have.
My camera has 5.2 mega pixel, but I use 3 most of the time because it gives great results, is faster, and takes less memory. Also, it only has a 3 x optical zoom and 7x digital zoom. I never use the digital zoom because making pictures larger works better on the computer. This is an old camera, but everyone is impressed with the quality pictures it takes ... like magic.
Check with the Geeks in several stores and compare prices. Ask what cameras they own, but don't believe everything you hear. Once you select a camera read all about it in the owner's manual. Just learned that my camera has red-eye prevention and correction. It also has adaptive lighting. You may be able to view the owners manual at this link, but will need to Login. http://www.retrevo.com/s/di
