2. Enable VRR/Gsync in LG's Game Optimizer menu
3. In CRU edit HDR Static Metadata and set Max and Avg Luminance of 128 (it seems like ANY edit will do. I tried deleting 4096 resolutions too).
4. Reboot
5. Disable VRR/Gsync in LG's Game Optimizer menu
Result: black screen. TV no longer receiving a signal

More findings: if I re-enable VRR/Gsync in Game Optimizer after I get the black screen, the signal to the computer comes back. Also, if I first disable Gsync in Nvidia Control Panel and then disable VRR/Gsync in Game Optimizer the signal from the computer to the TV is not lost.

That seems like an NVIDIA driver bug. Usually disabling VRR/G-SYNC in the TV will change the EDID, which should appear as a separate entry in the CRU monitor list. Maybe the driver is getting confused with one having an override but the other not. You might have to make the changes with VRR/G-SYNC disabled first, then enable it and make the same changes so both entries have overrides.
