I've been using two Dell P2715Q 4K displays with my nMP since they came out, and they have been working well.
I just installed the latest developer preview of El Capitain (10.11.2 Beta), in order to fix major issues I've been having with my music stuff (sound card issues, etc)... and now I'm having sleep/wake issues with the Dell's.
It's very frustrating, I can come back to my machine, and the displays won't wake up. I've tried powering them off and on, reconnecting the mini display-port cable, and nothing fixes it.
I can SSH into the machine, however, so I know it's not totally dead. I then have to issue a reboot and start off where I left off.
I swear in the past this MAY have also been related to leaving VMWare Fusion running in the back ground (based on simply correlating when it happened to what I was doing at the time). But it may not be as well.
Anyone else have these issues again? It's VERY annoying.
