           Summary: Plasma didn't appears on the seconds screen if it
                    connected through type-c to hdmi converter
    Classification: Plasma

SUMMARY
When I'm connecting a type-c "mini dock station" with an HDMI output, plasma
does not persist on both screens (the second output is just black) even though
the screen is fully functional. I can configure it and move windows there. It's
an interesting effect that when the systemsettings are on the internal screen
and I set the external output as primary, nothing happens — plasma remains on
the internal screen. However, if I move the system settings to the second
screen and apply the same setting, plasma jumps to the second screen, and the
internal screen goes black (though still functional). I can reproduce this on
two notebooks(AMD and Intel), and it seems to be a Wayland-only problem.
I don't know what logs could be useful, let me know if you need anything
additional.

STEPS TO REPRODUCE
1. Connect seconds monitor through typec-to-hdmi converter
2. Configure as extended output
3. Try to achieve plasma on both screen

OBSERVED RESULT
Plasma can persist only on the one screen

EXPECTED RESULT
Plasma appears on both screens, with no black second screen
