Upgrading to Ventura and resetting resolved the issue for me. I had previously been using the beta version due to this issue. The better display app did not resolve the issue for me, and there are other known issues with external monitors on Ventura that you may encounter.

Oh wow, I was going to ask about this. Thank you!

What do you mean by "reset" exactly? You mean any and all display changes I've made?

I wiped it clean during installation so no previous settings.

The HDPI icon pop ups automatically on ventura in display settings.

I would also change the cable and try a different one if that doesn't work. Sometimes the DP cable end up causing issues with monitor recognition.

Upgraded to Ventura, but didn't help display issues unfortunately. I've got a thunderbolt cable that came with the monitor. I've tried that as well as two different HDMI cables. My MBP doesn't have a DP input. Is it worth trying DP with a DP to USB-C adapter? I may have one laying around somewhere.

No. I meant if you have a DP to USB type C cable, you may switch to see if issue resolved.

Try plugging it in and out a few times (yes, it worked for me when it went back to not recognizing).

I have the same mac but a different 4K monitor. Sadly, I don't know any other solution.

Macbook display and scaling handling on external monitors is one of the worst I have experienced by a long margin so know you are not alone.

Got it, thank you. Unfortunately I'm not in a position to do a clean install at this moment without some interruption to my work, but I'll try that later if I need to.
