I hooked up an external projector display to an iMac. &nbsp;Then I made a setting change that made the screen black. &nbsp;How do I get rid of the setting? &nbsp;Safe mode allows me to use the external display properly, but when I go back in as a user it goes back to the black screen. &nbsp;Is there a file I can toss? &nbsp;Also, I created a new user account and it goes black on that account as well so this is a system setting issue and not user specific.

I hooked up an external projector display to an iMac.  Then I made a setting change that made the screen black.  How do I get rid of the setting?  Safe mode allows me to use the external display properly, but when I go back in as a user it goes back to the black screen.  Is there a file I can toss?

iMac external display, can't find way to change preference
