I am trying to configure an external e ink display (dasung paperlike HD).
No plug and play is working as it is considered to be. Here is maybe the issue:
~$ xrandr -q
xrandr: Output HDMI-1 is not disconnected but has no modes
Screen 0: minimum 320 x 200, current 1280 x 480, maximum 4096 x 4096
HDMI-1 connected (normal left inverted right x axis y axis)
DSI-1 connected primary 1280x480+0+0 right (normal left inverted right x axis y axis) 0mm x 0mm
I’ve had mixed success - depends on the cable - the Micro HDMI is delicate - I have a Micro HDMI to Mini HDMI - gaming flat screen that works well - my full size monitor doesn’t recognize it but I think it is a faulty cable. you also have to ENABLE the devterm to recognize an external monitor when it it plugged in.
