I'm trying to get the 1080p 60hz monitor to run at 4k 60hz. No matter what I do to that monitor in CRU and how many times I run restart.exe or reboot my PC the highest resolution Windows will show is 1920x1080 (Recommended) for that display.

I tried adding a 4k detailed resolution, I tried adding a 4k HDMI resolution and also a 4k TV resolution with CRU, nothing worked. Then I tried to edit the present 1080p resolution but no dice, Windows doesn't see the 4k resolution at all, can someone help me out here?

The first post describes the pixel clock limits you're encountering, and chances are a 1080p monitor will not accept UHD 4K anyway. You should enable DSR for the 1080p monitor in the NVIDIA control panel if you want virtual UHD 4K.
