MacPro (MId 2010) with dual Apple Led Display connected to mini displayport. one of them was in black even rebooted repeated. sometimes, if reset the SMC, the black one was lucky sometime to light on again but dim; sometimes it is normal.

I reinstalled the Mac OS sstem once, it runs well in one week. But then it turns back to be balck again.

The display card is ATI 5770. I doubted the Mac OS 10.8.2 has bug for the display driver.

LED Cinema Display (27-inch), OS X Mountain Lion (10.8.2)
