i have the exact same issue on a 42'' HDTV running the same mobo a 2600k and the HD6950 i have tried everything full formats and reinstall of windows, bios flashed to newest version, reinstalling graphic drivers and still same error and when i go into advanced from ezy mode i end up with graphical errors and still only half the screen
I have the same issue with a P8P67 LE + MSI HD 6950 + Samsung 46" HDTV using HDMI (tried DVI also), black screen @boot (the mobo doesn't show the bios prompt screen), press DEL to enter bios and only see 1/3 of the bios options plus the graphics are messed up. Had an Nvidia GTX 285 before and there where no issues. Really need help on this.
People aren't ignoring you but rather as of right now I think the issue is that nobody has a fix for it. I have a M5A97 board with the same exact issue with a Radeon HD6850 and i have been able to confirm through other forums that this is not an AMD/Radeon issue but simply how ASUS has programmed their bios. I am keeping an eye on a few forums if a solution comes up but i have yet to see one.
Sorry for the bad news but at least it's some kind of news.
