--- Comment #6 from Jakob Petsovits <jpe...@petsovits.com> ---
John's comment #3 spells out the gist of it, let me repeat and confirm this.
For external monitors, Plasma will apply an intentional, currently hardcoded 1
second delay before writing brightness values. This is to minimize writes to
the monitor's built-in storage, which for some monitors can wear out within a
few years if writing to it several times per day. Ideally we want to avoid
writing a barrage of brightness values when the user drags the brightness
slider or presses brightness keys several times in short succession, that's
what the delay achieves.
We adopted this behavior and timeout value from Dell's tools for Windows. It's
a little annoying because the monitor could react much faster, but still better
than getting user reports in a few years saying "Plasma killed my monitor
early".
Now, one could make an argument for making this configurable. I think the
current Display Configuration settings page is already way overloaded, if we
decide to add such a setting then we should probably wait until that page gets
reworked into several sub-category tabs or such. I'm not 100% convinced it's
necessary, and might not work on that kind of checkbox myself, but interested
in hearing other opinions.
