Good TV, might not be the best monitor for what you want. Main problems would be it's 1366x768 res, 8ms response (which isn't bad, but not the best) and apparent lack of 1:1 pixel mapping. Meaning the PC will be outputting say, 1280x720 or 1920x1080 and the TV will have to rescale this res to it's native 1366x768 res, meaning you won't get pinsharp text, images, windows etc from the PC or the PS3. Basically it won't looks like a PC screen does
