2x Sapphire AMD 6950's in crossfire.
AMD Catalyst Driver Version, and Driver History
Currently using 22.214.171.124
Have tried 12.7, 13.2, 13.5, 13.10, 14.4 (pretty much everything)
Windows 7 Pro, newest service pack.
I have two montors, one ASUS PB278Q and one Samsung. The Asus will run at 2560x1440 and the samsung will run at 1920x1080 currently. The issue is when ever I update my drivers, I no longer can use both resolutions. It does not matter what driver I try, the higher resolution on the ASUS disapears. I have tried updated the ASUS driver, switching from display port to HDMI and back, nothing. I find this funny, as it works on older drivers, but not on the newer drivers.

Applications and Games
Windows, and any game I play, as the resolution will not show up.
Intel i7-2600K, not overclocked.
Motherboard BIOS Version
Award Modulat BIOS v7.00PG
System Memory Type & Amount
16GB Ram, Corsair Vengence

This only happens when I update my drivers. This has become an issue as I can no longer update my drivers to play games at the fullest resolution. I have no idea why a new update would cause my resolutiuon to disapear and not be able to be accessed.
