You have a very bright room. LCDs are generally brighter than plasma TVs, and their screens are less reflective. That makes them better for daytime viewing in rooms with lots of windows or for night-time use in rooms with bright lighting. Some plasma TVs can look a bit dim in bright lighting when set to the normal or standard mode, which we generally recommend for home use. You can switch to the vivid mode or raise the brightness control to compensate, but the picture quality might suffer. Another issue with most plasmas is that the glass screens are subject to reflections and glare. If you have the lights on while watching dark scenes, you might see mirrorlike reflections on a plasma set.

For heavy use with video games or as a PC monitor. Both types of flat panels can do the job, but with an LCD, there's no chance static images will burn in. With a plasma TV, burn-in is a concern with video games, computer programs, and TV programming that has fixed images onscreen for a long time. That includes station logos, news tickers, even the bars alongside standard-def pictures. Many plasma sets have screen-saver features to minimize risk, but burn-in is still possible.

With either an LCD or plasma TV, consider a screen with 1080p resolution for use with a computer. The higher resolution will let you see more content onscreen with greater clarity and finer detail than on a 720p set. (You might have to connect your computer to the TV via an HDMI input to get 1080p resolution and to avoid having outer edges of the image cut off, otherwise known as overscan.)

For somewhat lower electric bills. LCDs tend to use less power than comparably sized plasma TVs. It doesn't appear that the differences would affect your electric bills by more than a few dollars a month in many cases, so that might not be a major factor in your decision. But there is obviously an environmental advantage to using a less power-hungry TV.
