skullmonkey Posted December 4, 2009 Share Posted December 4, 2009 When I start the PC I can see everything on my second screen (using HDMI) till the desktop itself. I even see the command lines in -v while loading then just when I need to see the wallpaper and taskbar and everything it turns off the second display. Can someone tell me what might be the problem? Im on Snow Leo 10.6.2 Thanks, s@ Link to comment https://www.insanelymac.com/forum/topic/200951-4870-turns-off-second-display-after-boot-up/ Share on other sites More sharing options...
Alex HQuest Posted December 5, 2009 Share Posted December 5, 2009 Problem is on ATI drivers. This is a common behavior for a dozen cards (mine included). If none of available options worked for you (DVI dongle, EFI strings, PC-EFI + GraphicsEnabler, 10.5.7 ATI drivers, EVOEnabler), so far there is nothing to do except go NVidia.
