Using an HD6570 w/1GB. Upgraded monitor to a Dell U2713, which supports 2560x1440 on DVI. Card does too (supposedly). But while the scaling is fine, the picture is almost totally red, with snow like in an old TV picture. The color goes way off when it boots into Windows 7 and the Catalyst 14 driver takes over (latest driver). VGA and HDMI work fine, as does DVI on 1920x1080 (NOT 1920x1200--all red with snow again). Swapped cables, even had the actual monitor replaced--same red tinged screen. Anyone have any ideas? Could it be the monitor timing?
