If your display ever looks like that. IE. having a loss of colors and looking like an old monochrome display on acid, try resetting your PRAM. This portion of memory on the logic board holds your display and video information.
The sad part is that after talking with two different apple employees, niether had any idea what to do. One suggested a SMC Reset and I'm not really sure why but I figured I'd give it a shot. Needless to say, the PRAM reset worked which I thought of after one time when I was at the "Genius Bar" with one of our iMacs from work.
Also, the video card I have, ATI Radeon x1600, had been discontinued in June of 2007 and there are NO video drivers anywhere to be found.

Note: Mac OS X stores your preselected DVD region choice in PRAM for easy access. Resetting PRAM does not allow you to change the DVD region.
- Display and video settings such as refresh rate, screen resolution, number of colors
- Startup volume choice
- Speaker volume
- Recent kernel panic information, if any
- DVD region setting
