Cannot adjust brightness, hue, saturation
I cannot adjust the brightness, hue, saturation etc in any video player (Xine and Mplayer). In fact, I can't even adjust brightness in Quake 3. I have a very old monitor, so I really need to adjust the brightness in videos. I have no clue what I should do. Can anyone help??
