MacOS Monterey display resolution problem

Thanks, but to clarify I am not mirroring displays. I use it as extended monitor. I’ve done this for about 1y with my older macbook without any issues.

Tried both with no change. The necessary options that were there before the upgrade just aren’t there now..

Weird. The refresh rate option for 60 Hz just showed up in the drop down and now, it’s working. I’m good now, I guess. 🥴

this wouldn't affect those of us having the issue with a Thunderbolt display to mac connection.

I’m having the same issue after upgrading my MacBook Pro (2016/13”) to Monterey yesterday. My only refresh rate options are 30 and 25. I do not have the recommended 60 you show above. Additionally, the resolution of 1920x1080 is not an option. The highest in my options is 1600x900. If I check the box to show all options, I get nothing higher than the 1600x900. I have a Dell SE2722HX display set as Extended display. It worked yesterday prior to the upgrade, but no longer works today. Is there a fix for this?

On my Mac mini m1 with Monterey a similar problem. Suddenly my monitor has to cope with a bigger screen. So my monitor a LED Cinema Display, only gives a view off a part of the screen. With cursor keys on the keyboard I'am able to move the view; up, down, right and to the left. I don't know how this effect is enabled. I can restart my Mac of course. But that is a Windows trick.

Via System Preferences > Displays to select 'Default for Display, helps that' does not work...

Did you try with the Option key down, that is, hold down Option and click Scaled?

Also, did you try setting the external display as the main display?
