Popped a 970 into the other PC so I can get 4k output to the TV. This is in windows 7.

 

Annnnnyway, whenever playing video, it has a giant tear in the picture. Any output, Any refresh rate, any resolution.

 

Reading around, lots of people report the same thing happening, solution is to turn on an aero theme. Which does seem to solve it but then windows will tell me after a while that its running bad and want to turn it back to a basic theme.

 

Has anyone else had this happen and found a workable solution which isnt something like keep turning aero back on, change to windows 10, or replace the card with something from team red, all of which I do not want to do.
