I just saw that you have a completely different PLNF, I will try that once I'm back home, with the cable unplug thing. Maybe that helps with my black screen.

BTW, did I understand that correctly, you DO have 4K@60Hz for external monitors available? I'm kinda locked on 2K@60Hz.

I gave up on hackintoshing my main laptop. It's really frustrating. No screen output whatever I tried. I'll try to get a output on a external monitor with HDMI. Maybe it'll help to get the internal display working..

Yeah, UHD620 is really frustrating... I'm also miles away from getting 4K to work, or even proper scaling with full image after sleep. Such a stupid issue.
