I have a 1440p monitor PB278Q and a HD7990 GPU.
A couple times a day (2 or 3) the screen randomly glitches for a miillisecond (the entire screen goes wierd).

The DVI Settings in AMD Catalyst Control Center don't change anything.
What could it be? Is it important?

Yes first check for any loose connections or bad cable. If the problem persists then you can test the system with another GPU and PSU.

Thanks. It's stopped now since I realised I was only used one gpu on the dual gpu HD 7990.
Not sure how that happened, but i reseated th GPU and now it all works fine.
