If only using TV for gaming, apply the game input go into Nvidia control panel resolution section and change the color settings to YCC 444 or RGB Limited.

This will match game console style output for use with the game preset on the TV and desktop text may look a little off but that is a compromise for better game image quality.

LG has a PC RGB 444 mode built into the TV by changing the input icon to PC but it has banding issues particularly in HDR that can affect image quality.

LG's HDMI-VRR works with HDR too.

The firmware update just makes the TV certified G-Sync the latest driver from Nvidia already works with G-Sync on the TV.

AMD is working on HDMI-VRR support too, it is coming.
