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)

    Hi, does it see it if you power OFF/ON or disconnect/reconnect the monitor?

    Power off on no, but there are 2 power switches on the HP ZR30W, one soft one hard. So soft no. Disconnect and reconnect I never tried. I didnt think MDP was hot pluggable.

    Well I just got off the line with HP tech support.

     

     

    They blamed the video card saying the display adapter in the mac mini is an embedded and not a workstation video card. In spite of the fact that displayport is a standard they insisted that the since the display adapter is not a slot in card that was the cause of the issue. Thats an excuse and I plainly told them so. So he offers to send me a new replacement. Several times he refers to a new replacement until I ask if it is refurbished and then "oh yes it would be a refurbished one". Meh. Thats the last HP product I buy.

     

     

    Its a nice monitor I will admit that. But you cant blame the video card if it is outputting a standard. And you cant replace a week old product with a refurb.

     

     

    From what HP tech support said the ZR30W is not compatible with any apple product except for the mac pro. Wishing I had bought the apple cinema display. This is a major PITA.

    It's 2016, and I'm running a Mac Pro with two displays. One is a normally functioning Samsung U23D970, purchased recently. The other is the misbehaving HP ZR30w which is about 3 years old. When it was a single display on an older Mac Pro, it was fine.

     

    However now, it intermittently won't wake from sleep. The Mac believes there are two computers connected, but the screen doesn't turn on. I can yank the Display Port cable for the HP monitor out, and the Mac snaps to 1 screen. Plug it back in, and both monitors wake up and are seen by the Mac.

     

    It doesn't matter which port the display is plugged into. If I use VGA or DP. I certainly have enough video card to power another 4 monitors this size.

     

    Did you have any luck?
