--- Comment #4 from NW <nw9165-jjnfov5...@yahoo.com> ---
1% might indeed be the sane default minimum value in this case. That said:

Some other software solutions solve this by allowing users to adjust the
minimum and maximum value of the screen brightness slider, example:

https://github.com/xanderfrangos/twinkle-tray/issues/484

Can a setting be added to KDE Plasma (to System Settings -> Display & Monitor
or Energy Saving or similar) to allow users to adjust the minimum and maximum
value of the screen brightness slider (perhaps with a note saying that 0% can
result in the backlight turning off completely on some monitors)?

That way KDE Plasma users could retain full control over the screen brightness
and would still be able to set it to 0% where desired (while 1% could remain
the default minimum value).

Otherwise KDE Plasma users would need to use alternative third party software
solutions such as https://github.com/davidhi7/ddcci-plasmoid for example (which
currently is not working on KDE Plasma 6.0.x due to:
https://github.com/davidhi7/ddcci-plasmoid/issues/73 ). Which would be
undesirable, as KDE Plasma's built-in screen brightness slider otherwise works
rather well (except for the new 1% minimum value issue).

Another thing to consider:

Essentially all laptop keyboards (and many external keyboards) have hotkeys for
increasing and decreasing the screen brightness. And most external monitors
have hardware buttons and OSDs to adjust the brightness. Which means, even if
setting the slider to 0% would result in the backlight to turn off completely,
there would still be an alternative way to increase the brightness to a value
above 0% again in most cases.
