Can´t adjust contrast, saturation, brightness any more
 

Everything worked fine, suddenly I can´t do that with any movie. Does anyone have any idea what might have happened? Is it related to a DirectX issue? Any pointers will help. TIA.

Color Controls
 

Deleting the XML file did the trick. Thanks ! :)

I have the same problem. Deleing the XML file didn't do the trick for me.

However I just realized that I had installed Real Rhapsody and the controls had died after that. I uninstalled Real Rhapsody and the controls came back again.

Real Networks, the king of crap software.

Try resetting your adapter refresh rate to a lower value (60HZ or lower)

If you want to kill your eyes, do that.
