[SOLVED] Enabling G-Sync with EVGA RTX 2080 and Asus PG279Q

[marek_shields]

Hello folks,

I am having a bit of an issue actually getting G-Sync enabled on my rig. I have an Asus PG279Q monitor, and an older Dell monitor, with an EVGA RTX 2080 card. I went in the nVidia control panel, selected "Enabled G-Sync, G-Sync Compatible" and "Enable for windowed and full screen mode" from the "Set up G-SYNC" menu for the Asus monitor. I then went to "Manage 3D Settings" and I see that "Monitor Technology" is set to G-SYNC. Under the Vertical Sync setting however, I only see "Use the 3D application setting", "Off", "On", and "Fast" as an option where in some tutorial videos online I have see "G-Sync" as an available option. I did a clean install of the latest graphics drivers but that didn't seem to help. I honestly have no idea what I am doing wrong here and and advice on how to fix this would be greatly appreciated.

Edit: There are 3 reasons why I think G-Sync isn't actually enabled. First being that when I select the "G-SYNC Indicator" from the Display section on the nVidia Control panel, nothing shows up. Second, when I run the G-Sync Pendulum test, the only options I have are to turn V-Sync on and off. G-Sync immediately goes back to one of the V-Sync options. Third, the UFO frame rate test isn't ever able to sync the frame rate and complains as such.

Are you using the Display Port?

My Asus monitor is using display port. The other is using a DVI to Display Port adapter.

And have you tried getting the secondary monitor completely out of the mix? It's useful to make a problem as simple as possible.

After unplugging that other monitor, restarting the computer, enabling the G-Sync indicator, then re-launching the pendulum test app, it seems to be working now. Plugging back in the second monitor and restarting the computer again still has G-Sync working. Apparently I just didn't reboot it enough times or something

Also of note for those who might read this, the G-Sync indicator only shows up for G-Sync enable applications (apparently just having a G-Sync enabled monitor isn't good enough to show that indicator). Another thing to note is that the vertical sync settings no longer have "G-SYNC" as an option. You can set it to allow the applications to choose what to use which seemed to work fine for me.
