Umm, HdTv's arent really good w/ pixels... from what i understand, you get like 1080i which is the best.
I dont t hink it will run off of DVI but correct me if im wrong, i dont own a HDTV (Riche) so i wouldnt know... if its plasma, its gona suck. refresh rates on plasmas are so huge your mouse will ghost... LCD good for computer bc fast refreshes, plasma = good TV because its cheaper to make, and better picture quality...
your gona want a refresh rate above 65hz for it not to burn your eyes, i however would recommend anything over 75hz.
