majrul Posted February 3, 2012 Share Posted February 3, 2012 I've successfully managed to edit the FrameBuffer so that i can access the VGA port on my Laptop and connect and external display to it. But i am unable to get mirroring work. As soon as i select the mirroring option, the screen freezes with some light blue color background. Yes, i can see the same on my external display as well. So that means it's mirroring this blue screen on both the displays, but since the laptop freezes after this, it doesn't succeeds. So i think mirroring is working partially. Someone please guide!

jazzyguy Posted February 6, 2012 Share Posted February 6, 2012 We didn't have mirroring, but after the 10.7.3 update we now do. We also reordered some of our connectors, which did make a difference in getting mirroring. Link to comment Share on other sites More sharing options...
