I am currently using my Grandfather's iMac G5. I love it and it is an absolutely awesome computer, but the problem is that the display ssettings are off. The color looks completely washed out, and at some point I can't even read the text on the screen because the black isn't showing up against the white. My father has tried to come in a calibrate the settingss but nothing has worked so far. Has anyone else had this problem? And if so, how did you fix it to get it back to normal and so that all of the colors looked correct?
iMac G5, Mac OS X (10.4.10)
Try opening System Preferences->Universal Access. In the middle of that preference pane is a contrast slider. Try adjusting that slider.
