Ok now sell me a monitor that tracks the light level like my phone and adjusts its brightness accordingly.
Ok so most monitors sold today support DDC/CI controls for at least brightness, and some support controlling color profiles over the DDC/CI interface.
If you get some kind of external ambient light sensor and plug it into a USB port, you might be able to configure a script that controls the brightness of the monitor based on ambient light, without buying a new monitor.
There are actually some models already with a built in ambient light sensor. I don’t know how much of a convenience it would be, whether it would be distracting if small changes in ambient light make the brightness go up and down all the time. I personally prefer changing it manually - I have a macro pad with knobs which are mapped to do that.
I too, just disable the ambient sensor, but if I had to have one,
I’d rather have one that sends the sensor data to the PC, via an Open Protocol over DDC and let the KDE brightness setting handle the Brightness value decision (which would be easily configurable, of course).
