SUMMARY
Changing brightness using Fn keys changes brightness on the laptop display and
the external displays.
This feature might be intentional and it could be useful, but I think the
default (shortcut?) should affect only laptop and maybe shift+Fn would change
all displays if this is not a bug and we want to have this?
Note, this doesn't change the brightness set on the monitor/TV. If it is set to
50, it stays at 50 in the monitor settings, just displayed brightness is dimmed
down.
I probably missed the component, please fix if needed.
STEPS TO REPRODUCE
1. Connect laptop to an external display
2. Change brightness using the Fn keys -> Brightness changes on the laptop
display and on the external display
OBSERVED RESULT
Brightness changes on the laptop display and on the external display
EXPECTED RESULT
Brightness changes only on the laptop display
