Armbian on radxa zero doesn't produce picture on 1920x480 display

I have installed armbian on the zero’s on board emmc storage. I have set it up on a standard 1080p display to a usable desktop, then I powered it off and plugged it into the wide-screen display. Once the zero is powered on the back-light on the screen flashes on for a second and off. If anyone knows how to rectify this issue it would be greatly appreciated. I have already contacted the display manufacturer and they aren’t responding.

Prob not as likely that has no config for that display aspect which is also very rare 1920x480 is new to me.

There is an article on the start page that will give you a good starting point on how to enable a custom resolution but likely you will lose the boot cli.
Unless you can also create an entry in the DTB but if it works as a desktop via xorg guess no problem really.

Have you had any luck? I have the same 8.8 inch screen that works fine with my rpi4, but I cannot get it to work with my radxa zero
