While watching videos on my computer, the video contrast is reallly high and is all almost white. But my monitor contrast is fine. Its only when watching videos on Windows Media Player and on Divix. It also happens when watching movies/videos on the internet. But my desktop and other things are fine Its only when i watch something. The video gets really white. I can see the image but its really white to where it looks really bad. When viewing pictures and playing games it great but it happens when I go to watch a video.

Please help me
