If you want to toss a cup of coffee BTC bc1qwsgcvcp8ddhppx792rfyw2hwv62uzjsmt35wme
LG B9 TV is set to 4K 120Hz Full RGB 12 bit HDR10
4K Active resolution(3840x2160)
Total resolution 4400x2250

I have a video game running in the background and Nvidia control panel open to demonstrate that G-sync/VRR(Variable Refresh Rate) on and off position.
So in Nvidia control panel under
Set up G-sync
#1.
Check mark -Enable G-sync,G-sync Compatible
#2.
Select the display you would like to change- I picked LG B9 OLED
#3.Display specific settings -
How you can tell VRR is turning on/off is if you look at Total resolution 4400x2250 number .
When I put a check mark in the box ,it turns on VRR on and the number 2250 will start to fluctuate.
When I uncheck the box ,it turns off VRR and the number 2250 will go back to static.

VRR turned on under graphic settings in Windows 10 2004(not needed but does not hurt)
