While I was waiting on a reply I went ahead and tried both the NVIDIA control panel and CRU to side step the issue by running the panel at 1920x1080 to see if the higher refresh rates would become available. I assumed that since 1920x1080 @ 144hz was ~166hz on the pixel clock and 2560x1440 @ 120hz was ~183 that the screen would handle this just fine.G-SYNC monitors don't have scalers, so you can't send lower resolutions to the monitor.

I'm dreading having to replace my old 680 given that it plays all of my current stuff at more than acceptable settings.It's not listed in the specs, but the pixel clock limit is 540 MHz. You can try adding 2560x1440 @ 144 Hz as a detailed resolution with the "LCD reduced" timing option in CRU. That will keep the pixel clock under 540 MHz, but the monitor might not be able to handle timing parameters that low. |
