so i'm considering getting a dell 24" widescreen display. I was on the dell sight and there's this link saying to consider the 26" lcd tv as well. Both are about the same price and i was wondering what the difference would be. I don't have an hdtv so could i use the 24" computer display to watch tv in hd if i got a tuner? and with the xbox360 coming out soon i'll want to play those games in hd as well. what are the advatanges/disadvantages of using a computer monitor for movies/video games vs using a tv for computer applications?
