Custom Resolution Utility (CRU)

In my control panel it show up with 3840x2160 as being the (native) resolution, but there is also the true 4k resolution of 4096x2160, and it is clearly this resolution which DSR is using to create the new resolution, although it's not the one being used by the TV, nor is it a native resolution to the TV. Hence I am trying to remove this resolution to see if it fixes my problem.

I have tried using your tool and choosing "No extension block" and the only 2 "Detailed resolutions" there are 3840x2160 @ 60Hz (at the top) and 1920x1080 @ 60Hz. However after applying these settings and restarting the driver, only resolutions of 1920x1080 and below are shown in nvidia control panel and windows.

I am not sure why the display is no longer being detected as being 3840x2160.

You need to choose "Custom extension block" with NVIDIA, and you need to add HDMI support for higher resolutions to work, but 3840x2160 @ 60Hz requires HDMI 2.0. CRU doesn't have a way to add an HDMI 2.0 data block yet, but you can include it by importing the default extension block. Use MonInfo to export the full EDID to a file, and then use CRU to import the file. Then it will appear as a custom extension block that you can edit. 4096x2160 is probably defined in a TV resolutions data block and in the HDMI support data block. Remove those and 4096x2160 should be gone.
