Display Port Issues since CAT 13.x Update

[msaunders]

Hi

I am having an issue with my HD6990 and second monitor on the display port since upgrading to the latest CAT drivers. When the computer comes out of sleep/hibernation my second monitor does not retain the set resolution and I get and error onscreen

"The system has detected a problem with the connection between your computer and the DisplayPort display that will prevent you from using the highest resolutions and/or refresh rates"

Anyone else experience this and know of a fix ? Again its only happening on the latest drivers , if I roll back to the 12.10 for example, the issue is gone.
Tks
Martin

Found this old thread thru a search whilst trying to resolve another problem. Google 'Radeon Sleep Bug' - seems that it's a common problem with ATI cards - at least yours wakes up! Most people with Windows sleep problems end up with blank screens after wake-up.

I had to disable 'turn off monitors after...' in Windows power settings.
