I just picked up a couple of Gigabyte Radeon 4850's and can't seem to get them to output anything higher than 720x480 to my TV in Windows 7 using the latest Catalyst 10.5 drivers. At first I couldn't get anything to output until I checked force component video detection in the display options. I'm using a 7 pin S-Video cable for component out that I used with the previous Radeon card I had in my system. I know the cable is working properly with these cards because it outputs 480i fine.
The problem is that when I try to configure the display in the desktops and displays control panel where it allows you to select supported formats, whenever I do this and apply the changes, when I go back everything is unchecked, and I still can't choose any resolutions higher than 720x480. So, how do I force the system into thinking it can support 1080i (or even 480p), which it should support?
