Q: Mac Mini 2012 and HP ZR30W not waking from sleep
Hi all,
I have a mac mini 2012 connected to a sun x7200 on DVI through the HDMI port and a HP ZR30W connected via the minidisplay port via a Accell B119B-007J Mini DisplayPort to DisplayPort Cable. The issue is while the Sun monitor over DVI/HDMI works flawlessly, the HP ZR30W fails to wake up from sleep intermittantly. This can be either on initial power on or after the display goes to sleep. The ZR30W does power on about two thirds of the time. But it is a huge problem when it does not as I have to power down the mini and lose whatever work I am doing. So I am trying to figure out if the cause is the cable, the monitor, the hardware of the mini, the firmware of the mini or lion.
So far I replaced the cable three times, no change. Although I replaced for the exact same cable. I reset the pram and the smc. Reinstalled Lion over a internet restore. Current on software updates. No change in the behavoir.
I'm open to suggestions. Aside from this issue I am very pleased with both purchases. However its a deal breaker. I cant be losing my work three times a day. And running the screen 24/7 is going to kill it.
Mac mini, OS X Mountain Lion (10.8.2)
