My main PC is waiting on a part replacement so I hooked up my mac mini to my cinema 30" but it will only display at 1280x800. The specs say this mac mini can go to 1920x1200. It was doing 1600x1200 on my dell 20 inch before. Is there any way I can force it to that res or anything higher than 1280x800? It's the highest option listed in display prefs and it detected the right display.
