Cant figure out color issue with computer.'s a Dell and even when it's's still a Dell.
Have you tried the monitor on different system to eliminate the tower being the problem? Some have updated and/or rolled back drivers to help cure this problem, which seems to be a common issue with this LCD. Personally i think the contrast ratio is inadequate.
Good luck with your Delllll...

Sounds like a piture tube or internal video driver in your monitor. You probably lost the green channel. If the monitor is dated I would replace it.
