Since the computer will be running at 1080p most likely the refresh will be set to 60 FPS. This is where the PureVideo HD software helps but still isn't perfect. This software has been much better at doing the 3:2 pull down / de-interlacing than most TV's integrated chipsets. Try finding a TV that both the inputs and display panel can operate @ 24, 30, 60, 72 and 120 FPS. The 120FPS is ideal since it can be divided by 24, 30 and 60 evenly. This way you don't have to change your refresh rate depending on the content type your trying to watch. There is also some PC software that will auto lock the refresh rate to the current rate of the playing video. It was very cool if your display could do the correct refresh rates. I can't remember the name but I will try to find it.

Try to find someone you know with the display technology that your thinking about getting and see if they will let you come over a watch a movie or connect a PC to it. I personally get headaches when watching DLP TV's for more than 2 hours.

What size display are your trying to get? Can you control the light in the room during the day? Do you need to hang it on a wall? Do you have a spending limit? The technology is changing so fast in the HDTV market you might want to think about spending way less and just getting something that does 720p and then upgrading in about a year.
