Other laptops I’ve used have provided screen rotation via Ctrl + Alt + the arrow keys. That doesn’t seem to work on the P2 Max.
I’m currently using a free app called Screen Rotate from https://www.microsoft.com/en-us/p/screen-rotate/9nblggh3zd5h?activetab=pivot:overviewtab When running, it does allow for keyboard shortcuts. Ctrl + Alt + A for example, rotates counter-clockwise. See the settings in the program for full details.
Have you found a built-in keyboard shortcut that works, or a simpler solution? Please share if so.
