How to change resolution HDMI display (Armbian5.27)?

[icce 0]

@Fenn Do you still have to put something other on armbianEnv.txt and boot.cmd or just put extraaargs to make it worked?

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).

Thx mate..this is the right answer on question!

In Armbian-Config you can set the Boot-Env, there was :

 

disp_mode="1920x1080p60"  

 

I've changed that to "1280x1024p50" but still get the 1024x768.   

 

The TV-DVI-Input I use is a little bad so EDID does not work, but forced 1280x1024 works with my raspberry pi. 

 

Is 1920x1080p60 wrong syntax may be, may be something with -24@50 is needed?

Providing logs with
