aspin Posted September 28, 2011 Share Posted September 28, 2011 The main display always goes to sleep after a reboot and the only way to get it working again is to unplug the cable and plug it back in. I have four monitors connected to two identical video cards, ATI 5750. QE/CI is fully working, and the cards are being properly detected by Lion as ATI 5700 series. The main display not being on is the only graphics issue I am having. It is on during the boot process but goes to sleep after Lion has fully booted. Although the main display is asleep, I can see the desktop on all the other connected monitors. What can I do to figure out why this is happening?
