Screen rotation on macOS app
"Screen rotation option is not available on Mac OS X" don't work for extended displays/monitors. Please write workaround for this.
Rotation on the DisplayLink Manager is available from macOS 11 Big Sur and DisplayLink Manager v1.1 onwards. For previous macOS versions, DisplayLink classic driver stays available.
I was able to get this to work by setting my rotated screen as the main display. After that I followed the "CMD-Option" instructions and the rotation option appeared. After this I was able change the main screen back and the rotation setting stuck. It's a wonky work around but it works.
Is there any update on this?
this is a must!!
Seconded. Even following the suggested hacks (the article about holding the Option + CMD keys) only shows rotation for primary screen, not the external display.)
