I just got a Magnavox 40mf401b, which has an input specifically for HDMI-DVI computer cables. I plug it into the TV, and Windows seems to detect it with no problems whatsoever. All the options are there, the different methods of displaying (clone, extend, etc), resizing the desktop, everything seems to work like there is no problem. Except the TV displays nothing. I know for a fact it is not a problem with the cable or my computer, as the HDMI-DVI cable works just fine on another monitor I have. I also know it's not a problem with the new TV, because plugging my PS3 into the same HDMI slot on the new TV works without any problems. So if it's not a problem with my computer, cable, or the new TV's input, what the hell can cause it to detect fine, but not display anything? After trying various solutions that none of which worked, I eventually gave up on the HDMi-DVI cable, and use the HDTV Component Out cables for my Nvidia Geforce 260 GTX card. This works fine, it detects just like the HDMI-DVI does, no problems, and the screen displays fine too. The problem here is that the TV is a 1080p native TV, but I'm only able to select 1080i (1920x1080 @ 29-30HZ), not 1080p at all. The option literally is not even there to select. So, I either need to 1 (perfered) - Fix the HDMI-DVI problem, or 2 - Get the HDTV Component out to work with 1080p. Please help me with either of these. EDIT: I just relized that it's impossible to do 1080p via component, no matter what. So really, I just need help with the HDMI-DVI problem.
