Powercolor 7850 (previously had a 6850 in the machine which didn't have this issue... I bought a 7850 on the cheap and replaced it with that).
AMD Catalyst Driver Version, and Driver History
Windows 7 64-bit, with SP1 and all latest patches
When the screens goes into standby (I have set windows to put the screens into standby after 10 minutes), they don't always wake back up.
Sometimes if I move the mouse the screens wake back up fine - this is what should happen every time.
Sometimes if I move the mouse, the screens backlights come on... but there's no actual image. The computer IS still running fine. If I hit Ctrl-Alt-Delete, the screens back instantly back to life and bring up the main task manager window thing... I then hit the ESC key and it goes back to the desktop.
So that's the workaround for it... but it's annoying.

I used to have an AMD 6850 in the computer. I uninstalled the catalyst drivers, turned off the computer, removed the 6850, installed the 7850, turned the computer on and then installed the 13.4 drivers again.
Everything is working fine apart from this strange issue.
I installed the old 6850 into my daughters computer, also running the 13.4 drivers, and her computer doesn't have this issue. It's just mine with the 7850 that has the problem.
