Not sure if it is much of a help, but for the said display NVIDIA Control Panel under "Set up G-SYNC" tells me: "Selected display is not validated as G-SYNC compatible".

You probably just want to know whether the monitor can be operated with VVR on an nVidia graphics card. The answer is: Yes.

If you want to know if there really is a Gsync module inside, then the answer is: No.

Quite okay for the PS5, but the inch size is too small for me.
