I searched the internet for the settings needed to use the LG OLED CX TV as a PC monitor with 120Hz chroma 4:4:4 and Variable Frame Rate (VRR), G-SYNC, FreeSync. I found bits and pieces in articles, forums and videos, but I couldn't find the one and only complete story with ALL the settings needed.
This video shows ALL settings needed to get it to work ... in the LG TV, in Windows and in nVidia. You'll also need a HDMI 2.1 Ultra High Speed cable.
