i purchased a 30 inch Advent widescreen hdtv tv (1080i) progressive scan. it has dvi built in on the back. i have a 9800 pro 128 video card and i purchased a dvi-d cable connecting the pc to the tv. the problem- i cant get a clear picture over 800x600. i try the widescreen resolutions and its even worse. i have read about this and the powerstrip program hasnt really helped. i get the high res. but it isnt really clear. i play on using the hdtv as a full time monitor for video editing and recording bands. there will be no other monitor connected. i have read that pc dvi to hdtv dvi should give the clearest picture and i dont need the ati component converter to get the crystal clear pic, the dvi has been said to work. what are my options? how can i get the clear picture?
