My board is OrangePI PC. I use Armbian5.27_Ubuntu_xenial_desktop (kernel 4.10.1-sun8i). My display is "Innolux AT070TN90": 7", HDMI. I can't expose resolution 800x480. Prompt how to change resolution?
I ended up working this out with the help of this post - specifically, if you add the following to /boot/armbianEnv.txt, you can force the video mode.
I didn't have to install any extra packages or anything using Armbian Debian St
