Monitor is connected using a displayport cable provided by the vendor. Monitor only has DP and HDMI for connectivity - no Dual-link DVI. Right now I seem to be limited to 120hz within NVIDIA control panel regardless of the resolution chosen.

I'm trying to determine if this is a software issue that can be fixed using this software, a limitation of the 680's displayport or something else entirely. Any help is appreciated.

The patch does nothing for DisplayPort limits. You need a 900-series or newer card to get 2560x1440 @ 144 Hz.

Toasty thanks for taking time out to reply. As of right now my 680 will push 2560x1440 @ 120hz over displayport. 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.

The NVIDIA control panel doesn't expose anything beyond 120hz regardless of the resolution used. CRU mainly results in the monitor saying its not getting a signal. Any chance you know (or can point me to) the limitation on the spec sheet that is stopping this from working? I'm dreading having to replace my old 680 given that it plays all of my current stuff at more than acceptable settings.
