I've had problems with my TCL TV in 4K, when 4K 60Hz HDR10 is enabled(no problem using 4K 30Hz).
I tried the last three graphics drivers and including the last one, win64_22.214.171.12423 (I'm currently using this driver)
The problem is that you get a thin white flickering line at the bottom of the screen and sometimes also a strange hue on the screen almost foggy....
The problem was intermittent and present on blank screen, VLC Player Full screen and also Browser streaming. Sometime a reboot would make the problem go away but sure thing it would return. I tried different settings in the Intel 640 Graphic settings to now avail.
Today I tried installing 6323 again and at the end of each graphic driver install you get a tick box that say's "tick here if you want driver to evaluate graphic capability and enable AMBIENT Display". This is graphic driver install number XX and this time I did not Tick the box. End Result after 6 hours use.
I have NO ambient display, I also have no problems with my TV in 4K when 4K 60Hz HDR10 is enabled. I don't know of this is a magic wand but it might be worth a try if you are experiencing similar problems.
Thank you for your feedback.
It seems that you also provided valuable feedback on another /thread/129864 thread. Were you using the same hardware/software configuration on this thread, too?

I was wrong with the above statement. It turns out that sometimes when enabling HDR all seems OK. Until you Reboot.........
And other times the white line is there at once.
The problem persists. I think we have narrowed it down to the TV being the issue. As it happens I'm expecting a replacement TV tomorrow.
I must congratulate you on the timing of this post ;o).
I'm still not 100% sure that it's the TV but hopeful. I get the feeling that it's an issue with the combination of the NUC and this particular TV,
something is right on the margin, anyhow I will update when I have tested with the new TV. I'm attaching a picture showing the white line appearing on the bottom of the screen when enabling HDR.
Sometimes the line flickers and other times it's just a solid line. It's not a cable issue that we know for sure.
