either a videocard or a driver or a settings issue (of the video driver).
I'd update the driver, then try other settings and see if the situation can be normalized.
If not, my next step would be to swap monitors with another PC and see what happens on both.
My monitor won't display it's colors properly, here's a screen shot of it beside my laptop showing the color difference: http://img130.imageshack.us/img130/5248/img0002ygg.jpg
here's the wallpaper on the weird monitor:
here's what the wallpaper should look like:
I know the monitor isn't broken because i already shipped it to acer and they sent it back saying it's fine, but i cannot get it to work properly!
Also, when im booking into windows 7 and it shows the 4 balls going in a circle and then combining to make the windows logo, it looks normal, the colors just go weird after it has booted up fully
