I'm using rtx 2070 msi gaming Z and monitor iiyama gold phoenix 28” 4k which is contacted using Display Port cable 2.0. The problem is that I don't have Setup gsync option in nvidia panel . Any ideas why ???
I'm having a look at that monitor and I can't find a G-SYNC version, only Free Sync, are you sure that monitor has G-SYNC? All the models I can find online are Free Sync
install the latest drivers from nvidia.com, then on the monitors control panel make sure freesync is enabled, then g sync should show up in nvidia control panel.
