Nvidia control panel does not allow 4k120hz as a native resolution so I tried to use CRU to force it as it works as a custom resolution. When I try to set the refresh rate to 120hz at 4k on CRU the refresh rate turns red and does not allow me to set it. How do I fix this?

EDID detailed resolutions are limited to 655.35 MHz pixel clock. The only way to add 3840x2160 @ 120 Hz is either in a TV resolutions data block in a CEA-861 extension block, or as a detailed resolution in a DisplayID data block.

I added it as both of those blocks but the option still does not appear in nvidia control panel or in display adapter properties
