I recently got a second 24" LED cinema display (one at the office, one at home). I noticed a thread on Apple's discussion board that perfectly describes an issue I'm having with the new one - http://discussions.apple.com/thread.jspa?threadID=1902288&tstart=0 When connected to my MacBook Pro, the screen will randomly (2-3x/day) flash to black and then reappear. It's not losing signal or going to sleep, because my laptop screen doesn't switch on or anything. My other 24" ACD has never exhibited this behavior when plugged into the same MBP, so I'm thinking it's a hardware problem. Just want to be sure before I send it back. I've heard some rumblings that OS 10.6.2 will have some "graphic card fixes", wish I knew if this is something they're looking at. Anyone else have this problem?
