I installed Manjaro ARM KDE version using etcher on microSD card. It seems the OS loaded but I couldn't get display working. I only have old monitors, so I have to use HDMI to VGA converter.
I had used ayufan and mrfixit image and the display was working perfectly after I lower the resolution via extlinux.conf. In Manjaro, I also tried to set the resolution lower via setenv video-mode and bootargs but no luck. I didn't forget to run mkscr, too.
