I've recently acquired a new GTX 1080 and a 144hz monitor (Acer GN276HL) that happens to lack DisplayPort leaving the only option as DVI-D Dual Link. However, both Windows 10 and the Nvidia Control Panel fail to provide a 144hz option.
I've tested both the monitor and DVI cable on a separate test build (with Windows 7 and a Radeon R9 290) and it worked perfectly with the 144hz option being available in Windows. I've tried using the new GTX 1080 on this same test build and the same problem occurs with only 1920x1080 60hz being available. The same issue occurs across different NVidia display drivers.
I've also tried using the nvlddmkm patcher and CRU to force a 144hz option in both Windows and NVidia Control Panel, but the result was that the monitor failed to find a signal.
I've tested everything with only a single device connected to the GPU. I am not using any sort of adapter.
As far as I can tell, it's not specific to Windows 10 or 7. The monitor is perfectly capable of it in theory. And the cable works. I'm starting to run out of ideas besides trying a higher end cable as a long shot or believing in a conspiracy that the Dual Link port is actually secretly a Single Link.
