[RPi5] Rotate screen for Waveshare Portrait 1080x1920 5.5 inch Amoled Display

    Hi,
    I am using a Raspberry Pi 5 with a Waveshare AMOLED 5.5-inch 1080x1920 display.

    After installing LibreELEC, the display is in portrait mode (vertical) by its native resolution.

    I would like to use it in landscape (horizontal) mode, but it seems the rotate command is not working.

    Is there a way to rotate the display to 1920x1080?

    Thank you!

    Raspberry 7" Touchscreen Rotation LE 11.0.3

    I have a Raspberry Pi 3B with the official 7" touchscreen in a frame and have upgraded from LE 9.2.8 to 11.0.3. In order for the display to be the correct way up I added lcd_rotate=2 to config.txt in LE 9.2.8. This worked perfectly.

    Since updating to 11.0.3 I have been unable to rotate the screen. Below are the four separate additions to config.txt tried unsuccesfully.

    dtoverlay=vc4-kms-dsi-7inch

    video=DSI-1:800x480@60,rotate=180

    dtoverlay=vc4-kms-dsi-7inch

    panel_orientation=upside_down

    Video Orientation

    I decided it was time to update my Pi 2 running 9.2.8 to a Pi4 running 11.0.3. which was easy to do but now I have some changed behaviour with video orientation:

    On some of my home videos which were shot inverted I could change the orientation using either the metadata or by 180 degree rotation, no problem and it seemed to work seamlessly on the earlier version.

    With the newer version on the same videos from my server I can change the orientation by 90 degrees but selecting metadata or 180…
