Since Driver 13.11Beta and now with 13.12 I have a strange problem with my Radeon HD7970 and the two monitors.
I'm using Windows 8.1 x64, but I had the same problem with Windows 8 x64.
The energy options are set to turn off the monitors after 15minutes.
Sometimes this works like a charm, but more often one monitor turns off and the other one stays on and shows some strange pattern, which changes all the time
Here's a picture of this pattern: https://skydrive.live.com/redir?resid=298033BFFD625399%211091
As said. with 13.9 this didn't happen.
With 13.11Beta or 13.12 it happens in 3 out of 4.
Can somebody tell me where to look, or how to change this?
Here are my details:
Sapphire HD 7970 3G GDDR5 PCI-E (21197-00)
AMD Catalyst Driver Version, and Driver History
13.12, 13.11Beta several versions, 13.10 don't remember which.
13.9 worked and all previously also
Windows 8.1 x64
also tested with Windows 8 x64
as writen above
Motherboard or System Make & Model
ASUS P9X79 Deluxe
Seasonic X-660 (SS-660KM Active PFC F3) 660W
Display Device(s) and Connection(s) Used
2 Dell U2712
both contected with Minidisplay to Displayport Adapter and DisplayPort cable
It would be nice to solve this issue without downgrading to 13.9.
Thanks for your suggestions and help
