P2715Q, can't get 4K at 60Hz?
Hi!
I have a DELL XPS 8700, a monitor P2715Q and a EVGA GTX 750ti card, which supports 3840x2160 @ 60hz at mDP 1.2.
It worked for some days when, suddenly, I turned on the computer and the screen was black. I've set the connection back to HDMI and it worked. But I need to use DP to get 60hz.
Hope there's a solution.
Thanks!

Perform the no cable/power button reset
* Turn the monitor off
* Disconnect all cables from the monitor including the power cable
* Press the monitor power button in for 8 seconds
* Reconnect the monitor power cable and one video cable to the PC
