Hey everyone. Just want to put this out there to see if anyone else is experiencing this problem. I've got an HIS 6950 IceQ 2GB Turbo card that I've been using since day one with a Gateway LP2424 HDMI display @ 1920x1200. The latest driver that I'm able to use on it though is Catalyst 12.8. If I try to use anything more current than 12.8, I can't set the resolution to 1920x1200 without experiencing a rainbow effect and all text getting corrupted on screen. If I drop the resolution down to 1920x1080 everything is fine. I've tried pretty much everything and it refuses to work with anything newer than 12.8. I know it's not the system either; I just built a new system over the weekend and did a fresh install of the OS and tried using 12.10 right from the get-go. Same problem. I've tried looking for an updated BIOS for the video card but I haven't found anything (it's currently got BIOS rev 013.010.000.007.039363 (113-SS2G02-002) so I can't rule that out as being part of the problem. It doesn't look like HIS publicly releases their BIOS updates though (or I'm just not looking at the right place). So... anyone else experiencing this with their 6950 @ 1920x1200, or is this just a quirk of my particular card?
