I've never had any problems with driver updates before but the latest left me quite the mess to clean up.
I have a Radeon HD 6900 and am running Windows 7 64 bit. The latest driver Catalyst 15.7 (which contains display driver 15.20.1046) changed my resolution to something less than the native 1920 x 1080 of my monitor AND sized it so it didn't fit on the screen. It reported my resolution as 1920 x 1080 which it clearly was not. I tried switching to other resolutions and back, rebooting, unplugging and replugging the monitor so it could redetect it - no good. I finally did a rollback and everything is fine now.
You might not experience the same problem but just to let everyone know.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
