I just installed Ubuntu on VIM3 (from VIM3_Ubuntu-gnome-focal_Linux-5.7-rc7_arm64_SD-USB_V0.9-20200530.7z.) Maximum resolution is set to 1920x1080 but my monitor is 3440x1440. How can I change the resolution? I tried setting it in /boot/env.txt. Also tried script I found in the following post: How to change the display resolution of the Ubuntu on VIM3. Also found “HDMI resolution” GUI gadget. None of these three methods work. I also noticed that /usr/local/bin/hdmi.sh script is actually empty, and it looks like this is were the actual commands should be.
and it returned mode 1920x1080 as highest resolution, and also marked as “native”. I believe that HDMI on VIM3 does not read monitor edid correctly. Is there anything can be done about it, otherwise this board is not usable to me.
