Result
If you have switched on the display with a short operator action, it is set to the brightness
value set in the Control Panel, e.g. 100%.
If you increase the display brightness gradually, the brightness value set in the Control Panel
is ignored. If a brightness of "75%" is configured, for example, you can still set the display to
a brightness of "100%" by gradually increasing it.
