    Question HDMI Monitor no signal when joined

    Hi I'm brand new to Ubuntu.

    I'm running 20.04, freshly downloaded

    My LG HDMI monitor (second screen) shows up in screen display when I connect it. However I'm not getting any signal to it.

    When I run xrandr this shows up, not that I know what it means yet.
    HDMI-1 connected 3840x2160+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm

    I can use mirror mode, but when I try to join displays I get no signal.

    Halp a newbie please

    I posted this in Hardware as well, not sure where best to post

    Welcome.

    Please do no post duplicates.

    If mirror mode works but extended doesn't that means that means you're using an incompatible resolution.
