Unable to get Gsync working

Dual booted PC, Gsync works on Windows. When booting into Windows, the display (LG C9 TV, explicitly Gsync compatible) shows a popup alert: "The Instant Game Response is launched". This alert does not appear when booting into Arch.

On Arch: I have an Nvidia card (2070 Super) so am already on Xorg (which seems still to be a prerequisite for Gsync on Linux, Wayland still only partially supported). It's connected via active HDMI cable. Both the card and the TV are HDMI 2.1 capable. In nvidia-settings, display device information reads:

G-SYNC Mode Available: G-Sync Compatible
G-SYNC Mode Enabled: Yes

PC was previously physically connected to two displays, the DE (Gnome) recognised my normal monitor as display 1 and the LG TV as display 2. When the TV is connected, display 1 is disabled via Gnome's GUI settings. I did read on a few forum posts that having two monitors connected can kill Gsync, so the PC is now connected to the TV only.

The instructions on the wiki (https://wiki.archlinux.org/title/Variab … a-settings) have been followed and in fact recommend the defaults in nvidia-settings.

As far as I can tell, I have everything covered and this should be working. Anyone have any ideas what I might be missing here?

Driver version:

$ nvidia-smi
