I have an HDTV that I'm hooking up via DVI to HDMI from my Mac mini. In my struggle to eliminate overscan I managed to set the screen resolution to something not supported by the tv. How do I change the resolution without that screen attached?
Specifically my tv says it's "720p and 1366 x 768 Resolution". The 720p resolution option in OS X made for a ton of overscan (couldn't see menubar or dock at all). So I tried something x 768 and managed to shoot myself in the foot with an unsupported resolution. I thought it was okay to experiment since a resolution change times out if you don't accept it. Apparently that didn't happen for some reason. I've already deleted the com.apple.windowserver.plist in /Library/Preferences as I saw suggested in other places, with no effect.
I should add that if I boot with the TV attached I get a signal, but once I log in again it switches to the unsupported resolution. – Brad – 2010-10-15T13:37:47.983
When you write "deleted the com.apple.windowserver.plist in /Library/Preferences", do you mean what I suggested? Filename and path are different, therefore I have to ask; since you didn't follow up on my answer. – Daniel Beck – 2010-10-22T20:49:49.967
