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.


It is proven here: Black Screening / Video Card output switching off from iCUE - Page 4 - The Corsair User Forums


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.
