I experienced Black Screen issues since May. Tried all different drivers all the way back to last year, did not help. For a month i though it was CAM software from NZXT, it partially was.
Basically narrowed down to iCue software from Corsair and NZXT CAM. They both use CPUIDSDK.DLL & CPUIDSDK64.DLL. And probably a bunch of other monitoring software use the same DLL to check on your sensors. Those DLL crash the Display Driver for some reason.
First off all if you have any iCue or NZXT CAM - Uninstall, after that do a search for CPUIDSDK.DLL and the x64 version and rename them.
I am running 1 week free of black screens, my Display Port gives me "Display Port Link Failure" after monitor goes to sleep but i guess that is a separate issue.
Anyway, hope it helps.
