I've been beating this up for a couple weeks now, and although some progress has been made I'm still not where I need to be. The entire detailed thread on avsforum is here: https://www.avsforum.com/threads/new-lg-...t-62116130

Reverting to a specific older Nvidia driver helped some of the issues, but at the end of the day I am still unable to choose any 4K PC resolutions above 60Hz in the NCP. The TV goes dark and says no signal. I can VNC into the PC and see the desktop. The computer itself will accept the 100/120Hz 4K settings when they are selected, the TV just loses sync.

I ran the CRU utility and exported the EDID. Have attached to this post. Hoping there is useful info in there, or someone here has some ideas. AM open to all suggestions.

Honestly, it sounds like there's a hardware problem somewhere because this setup should work without problems. The EDID is fine, and the PC recognizes the resolutions, so the signal is getting distorted somewhere. You mentioned trying other cables, so I think either the video card or the TV is defective. If the video card has another HDMI port, try that just in case the HDMI port is bad. Try another HDMI port on the TV as well.
