I've been seeing ads in the paper for digital tvs that are hdtv compatible and so on. I dont mean the super expensive plasmas, but the 2000 dollar or so 50 inch digital ones. Do these have any DVI input, or way of connecting to a computer. I am looking for a solution for a home theater with computer set up, but the quality of video out i get from my radeon card is insufficient. Anybody know about these?
