I recently upgraded to an intel 8700k and the EVGA Z370 Classified K motherboard. After a lot work hunting for drivers, I was able to get the UHD advisor tool to indicate that I had "passed" all the requirements except two. I am still failing the HDCP 2.2 check and the advanced protected audio video path.
I have configured my BIOS to only use the 8700k's integrated graphics, and I am connecting a 18gps cable directly from my motherboards HDMI 2.0a slot to another HDMI 2.0a slot on my display, a Sony X800d TV. The Sony's specs indicate that all the HDMI ports are HDCP 2.2 compliant.
I would appreciate any help in getting this matter to work, thanks in advance.
