This has happened without me being able to figure out why. Suddenly the colors in fullscreen has changed to a very bright color when playing mpeg2 (.ts file). It seems that the brightness has been turned on (black is grey). I have tried using WMP in fullscreen, also with purevideo decoder, and it is completely normal.

How can I change these settings? I have tried the nvidia settings, but they are set to default......
