Apple Event: May 7th at 7 am PT
My iMac's screen (3.4 GHz Intel Core i7) is stuck on 1280x720. In the display settings I can choose between 1280x720 or 800x600. I've tried to log out and restart with no luck.
The only additional program installed is a Wacom driver.
Does anybody know what this might be?
Thanks!
