How to rotate External Display screen vertically, connected to Mac mini.

I have a lenovo external display plugged into my Mac Minin (M1, 2020, Ventura 13.6.6) directly to the HDMI on the back of the mini.

But, I'm not able to rotate the screen in Settings. See screenshot.

I've uninstalled 'DisplayLink Manager' as I've seen that in a couple threads but that didn't resolve it (even after restarting computer).

Also tried the 'hold Option down while clicking on Settings' but that didn't do it either.

Any idea what's going on here?

Thanks

PS...the other display ('LEN...') is a mirror.

Having that mirrored display is probably what is preventing the rotation.

Try setting the other display to extended desktop, then you should be able to rotate.

Then if that is what you want, try setting the second display to mirroring again.

That was the culprit.

I 'un-mirrored' and was then able to rotate the screen.

Thank you Luis!

This is what I see for my 90º rotated screen.

Did you click on the screen you wanted to rotate?
