Beware: 10.11.2, Mac Pro 2013 will not wake up 4k Displays

From the release notes, it looks like this issue is fixed in 10.11.3. I just installed the update so I'm anxious to see if it's really resolved.

That would be awesome...Let us know what you find.

After a couple of days, so far so good. The displays have woken up every time I've prompted them to. I'll try to report back again after about a week to give it some more time and see if it's really fixed.

Configuration: 2013 Mac Pro, dual P2715Q, running 10.11.3.

Awesome, I might have to go back to my dual setup as well. I went back to my Apple displays because it was such an issue for me.

Still working without any problems in 10.11.3. I'm considering the issue fixed.

Same here. So glad this got resolved in one update interval.

The only way for me to wake up the monitor is to unplug the power connection to the UPS. Very frustrating to continuously crawl under the desk to perform this task just to get the monitor to display.
