Official Android 11 image
Please describe your issue below:
I am trying to get my 8:3 1600x600 (Waveshare 9.3 HDMI LCD) working with Khadas VIM1S running the official Android image. Unfortunately, VIM1S is only detecting it as a 1920x1080 device, which is just wrong. I have also tried changing the resolution using the android wm size command, and it just shrinks the screen, and does not display correctly. This display works perfectly on my Raspberry pi, and Windows PC.
Post a console log of your issue below:
Here is the EDID from the display. Furthermore, they have the required HDMI published:
