Screen dimming is technically possible over HDMI/Displayport no idea why its not properly supported and integrated into monitors, graphics drivers, windows and Linux. KDE shows dimming for monitors sometimes? Don't know of that is software or real hardware dimming though.
It’s real hardware dimming.
Nice thought so but wasn't sure.
I’m talking about brightness in context of 3d. KDE uses DDE with USB connected monitors which is the same thing as using a button to lower brightness.
