Most of the time, under Linux the Asus PG32UQX monitor isn’t detected as GSync capable. This is most likely a driver bug.
Fortunately, there is a work around:
- Open nvidia-settings
- Go to “X Server Display Configuration”.
- Click on the “Advanced” button.
- Check “Allow G-SYNC on monitor not validated as G-SYNC Compatible”
- Click on apply.
I don’t think there’s a way to apply this setting via the CLI, but I’d be happy to be wrong about that. :)
Hopefully that helps someone… Hopefully this gets fixed soon.
