Gsync only working on one monitor

[terley]

Hi guys,

I am trying to get Gsync working on both of my monitors:

Acer predator xb271hk
3840x2160 IPS Gsync 27" 60hz

&

AOC agon ag271qg
2560x1440 IPS Gsync 27" 165hz

I'm using an ASUS Strix GTX 1080ti OC, but when playing games on the Acer i am noticing visible screen tearing with vsync turned off, when using the AOC i get none..

The Nvidia control panel doesn't seem to provide any answers, the Acer does say "G-sync mode" when going through the OSD, but it just doesn't feel right..

I thought you could only use GSYNC on your primary monitor? Could be wrong...

I believe you would need to GPU cards to be able to run Gsync on multiple monitors. 1 GPU for each monitor.
