Hi, working on Rock Pi 4B++ and trying to make our displays work. Armbian Bookworm 23.8 Raspberry Pi 7" official touchscreen Officialy supported by Radxa (https://wiki.radxa.com/Rockpi4/Raspberry_Pi_official_LCD) but it does not work on Armbian at all. Works on official Radxa Debian image. No display on Armbian. Using device tree overlay from Radxa image - does not work, of course. Waveshare 4.3" touchscreen HDMI (https://www.waveshare.com/wiki/4.3inch_HDMI_LCD_(B)) It works. Image is visible, touchscreen works but the resolution seems to be scrambled. It is 800x480 and it is correctly reported, but the image is somehow distorted. I guess the problem is the aspect ratio which is 15:9. On Raspberry Pi, it works correctly but the following settings is required: How to correct this on Armbian? Waveshare 4.3" touchscreen DSI We also have DSI version of the above display. We have not tried yet but I guess what the result will be, right? So my question is How to make these displays work correctly on Armbian? Thank you.
