just recently i noticed my screen is much darker than usual. ive tried turning it up really high in the control center but it doesnt do very much. then i noticed that it goes back to normal when i open the catalyst control center. but then it goes back to dark if i minimize it, go to a full screen program...no general patterns really just whenever it feels like it. like i can open up the control center and it will be bright, open up css then minimize back and its dark again. any suggestions? i also have the latest drivers (8.1) for my 2600xt 512mb card.
