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.
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.
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.
