solved: not plasmas fault: the monitors own smartcontrast did that.

Hi, please kindly direct me to the right community to ask this:

Plasma 6 is my favorite DE and i use KDE neon. The screen brightness adapts automatically to the windows i focus on, which is a good idea. But it does that the wrong way IMO. Dark windows are dimmed and bright windows are lit up. Why? Now i have both extremes switching back and forth all the time. Can we turn that the other way around or turn it off please?

I like that the screens hardware brightness setting is used now from the desktop. Great! But now i have no control over it anymore, since when i open a bright window, the brightness setting goes up too. I hate that at night.

Usually adjusting the brightness for me has one purpose:

…maybe something in between for transition. All the other features are nice to have but please only work on them when this main feature is secured.

I believe you’re talking about the challenges discussed here: …kde.org/…/brightness-controls-for-all-your-displ…

If both monitors are messing with your sensors, you may just want to disable adaptive brightness and manually control it. They don’t seem to have a workaround for it as of yet.

That’s probably the new Extended Dynamic Range setting from Plasma 6.4. You can find it in the display settings. It is meant to adjust the display’s brightness to emulate an HDR display.

I don’t want to be “that” guy, but enabling features added with an update by default is just not the best user experience (if that’s the case).

The screen brightness adapts automatically to the windows i focus on, which is a good idea.

That’s definitely not something Plasma is doing… Sounds like your monitor is dumb with “adaptive contrast” or just terribly implemented local dimming.

i think that was it, thank you! I must have enabled smart contrast which does that.
