I'm curious if I'm doing something wrong, or I'm just out of luck. I do have The correct monitor selected in the dropdown.

You need to be more specific. What monitors are these? How is each monitor connected? HDMI? DisplayPort? Is this a desktop or laptop? What changes are you making? Did you make the same changes on both monitors?

Im new to CRU. Im trying to create a custom 3840x2160 at 72hz for my LGTV C1 that's hooked up to my 144z computer. Im having issues though. So I changed the detailed resolution to 3840x2160 at 72hz. Next I tried to add to Standard resolution to 3840x2160 at 72hz because all the CRU tutorial videos show them changing the standard resolution to what they want to add before restarting it. But it won't let me. The numbers are in red. Heres pictures

You should really read the first post instead of following tutorials that don't explain anything and add unnecessary steps. You can't add 3840x2160 @ 72 Hz as a standard resolution, and there's no point in adding the same resolution twice anyway. Also, what you're showing can't possibly work because you deleted the extension block with data blocks required for HDMI. You're doing too many things at once. Just add a detailed resolution anywhere there is room, either in the main window or in an extension block. If there is no room, add an extension block. Then test if 3840x2160 @ 72 Hz works with your TV before doing anything else. If that works, then you can start deleting resolutions you don't need, but leave the HDMI data blocks. Also keep in mind 4K resolutions can be in several places: https://www.monitortests.com/blog/guide-...4096x2160/
