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.
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.
