HDMI on macbook pro 2012 retina stopped working.
I'm using the macbook pro 2012 retina. The HDMI out to an external monitor works stopped working recently and only works if I'm connected when rebooting. This might have happened after a software update. Has anyone else seen this problem or have any suggestions on how to fix?
MacBook Pro (Retina, Mid 2012), Mac OS X (10.7.4)
