How to change resolution HDMI display (Armbian5.27)? in Advanced users - Development Posted November 21, 2018 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. Some examples: 640x480 extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/640x480.bin video=HDMI-A-1:640x480-24@60 1080p extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:1920x1080@60 I didn't have to install any extra packages or anything using Armbian Debian Stretch / 4.14.78-sunxi, it just worked out of the box (edid files already installed/etc). 2

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.
Some examples:
640x480
extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/640x480.bin video=HDMI-A-1:640x480-24@60
1080p
extraargs=drm_kms_helper.edid_firmware=HDMI-A-1:edid/1920x1080.bin video=HDMI-A-1:1920x1080@60
I didn't have to install any extra packages or anything using Armbian Debian Stretch / 4.14.78-sunxi, it just worked out of the box (edid files already installed/etc).
