How do I reset Display Preferences with screen jumping?
Just got a new MacMini and connected it to my projection TV using S video cable. Everything was working fine until I tried to make the image look better and I guess I selected a wrong option in Displays System preferences because now yje image is just jumping and I cant see anything to set it up back the way it was.....
Thanks for the suggestion. However Apple Tech support walked me through it: I started it up in "Safe Mode" (holding shift). And was able to go to Display preferences and change the settings. After restarting everything was back to normal
