--- Comment #8 from Tjado Edzards <tj...@edzards.eu> --- Hi again. I got the time to check now. The issue definitely changed. I have brightness sliders for both monitors now. On Plasma 6.3.3, my secondary monitor (DELL) works perfectly. My primary monitor is detected, however the brightness control seems to fall back to darkening every pixel on screen or something. I started using Luminance ( https://github.com/sidevesh/Luminance/releases ) which can control both monitors correctly via DDC. So the issue is not with the monitor not offering the capability. I think this is still related to the original issue, as my primary monitor can still not be controlled via DDC. -- You are receiving this mail because: You are watching all bug changes.
