belgrano Posted May 3, 2006 Share Posted May 3, 2006 You can try to get other resolution (1280x1024) by editing com.apple.Boot.plist from /Library/Preferences/SystemConfiguration. But it's not possible to change the refresh rate. Link to comment https://www.insanelymac.com/forum/topic/16631-refresh-rate/#findComment-107173 Share on other sites More sharing options...

belgrano Posted May 3, 2006 Share Posted May 3, 2006 It's not possible to change the refresh rate since we (ATI users) don't have a working video driver. Useless or not, this is all you (we) will get... until omni finishes the driver.
