Bug ID: 481927

and color menu

SUMMARY
Since plasma 6 power devil seems to provide working brightness controls on
external monitors.
There is however, no way to control the brightness of individual monitors in a
multi-monitor setup via this GUI.
Observed result:
Only able to adjust all monitors at the same time.
Expected result:
Be able to control the brightness of individual monitors in addition.
Personal use-case:
I have a 4 monitor setup, but use 3 different types of panels, these monitors
have different brightness levels, adjusting all of them in one go results in
one monitor being significantly less bright.
I want to be able to adjust brightness quickly depending on how much light
enters my room from outside, the current setup does not work for me because of
the different brightness levels of my monitors.
I will also add that when you only have one type of monitor the current setup
works fine, per monitor control would only be a hindrance there. This is the
case for me at work.
Additional notes:
I believe this bug is different from:
https://bugs.kde.org/show_bug.cgi?id=470107
As this is about controlling the brightness of multiple monitors via ddcutil
rather than over two different methods of control. And it's about adding
functionality, not the control itself being broken.
