You'd be greatly dissapointed in the performance. I hate to burst your bubble. Even at 1080p, your TV is probably 1920x1080 resolution, while 22" Widescreen monitors are 1680 x 1050. So, your TV is roughly 1/2 the resolution. It would seem pretty grainy if you were up close to it. Get a 30" LCD Monitor. People 5 box on those. I use a 22" Widescreen and a 19" regular.
