If you check the monitor with CRU, do you see 3840x2160 @ 60 Hz anywhere including in extension blocks and TV resolutions? If so, delete it before patching the driver. You should be able to unpatch the driver in safe mode if it doesn't work.

Thanks ToastyX, this really pointed me in the right direction. I went ahead and removed 3840x2160 @ 60hz from the extension block, and it did boot correctly after that!

However, I still was not able to get 1920x1080 @ 120hz. Although I was seeing the option in both Windows display settings and in Catalyst settings, I would only get a black screen before going back after the 15 seconds.

I finally found the solution though: I had to set the bit depth from 10bit down to 8bit in the Catalyst settings. After I tried that, 1920x1080 @ 120hz was working like a charm!

Thanks for the help and for this amazing software!
