Is there a way to rotate a local HDMI display 90 degrees? I currently have a 400x1280 display that needs to be rotated.
I have tried configuring the config.txt with -
The above methods work if dtoverlay=vc4-fkms-v3d,audio=off is commented out but then I can't enable the display so all it shows is the HiFiBerry logo.
I then tried configuring the cmdline with -
But that does not work as well. Any other options?
