Don't mean to bump an old thread, but Armbian.com's 5.21 release and better have special settings to allow HDMI-to-DVI converters to work.
From here: http://www.armbian.com/pine64/
"Even if HDMI situation is still somewhat limited Armbian starting with release 5.21 supports setting the default resolution in /boot/armbianEnv.txt (defaults to 720p60 and could be changed to 4K@30Hz for example with an entry disp_mode=2160p30 -- for the list of supported resolutions please have a look into /boot/boot.cmd)"
