eagertolearn Posted March 22, 2009 Share Posted March 22, 2009 i wouldn't recommand chaning resolution on OS x, last time i tried it and i got kernel panic. U might want to try installing a different video card driver. I got 1024x768 on my first install, but on my second install i tried a different driver and i got 1680x1050 on my same 7900gs card Link to comment https://www.insanelymac.com/forum/topic/158677-cant-change-resolution/#findComment-1113117 Share on other sites More sharing options...
