Everytime I try to play a video (mpeg, avi, asf, whatever) it appears darker than it should, my monitor is on its highest brightness setting and For some reason I cant get overlay mode to enable on the nvidia control panel. I have a geforce2 ti. This problem also occurs in games. I have to adjust the brightness in any game i try to play due to this problem. Any help would be very much appreciated. Thanks in advance.
