   on Arch Linux, you can control the brightness of your external monitor via DDC/CI.

   I had to modprobe i2c-dev, install ddcutil and can now set a brightness with sudo ddcutil setvcp 10 20 where the 20 is the brightness.

   here’s what I followed: https://wiki.archlinux.org/title/backlight#External_monitors

     @kaia I once tried to control monitor rotation with DDC/CI. It seems Benq uses that with their windows driver but I couldn't get autopivot to work.

     @kaia The problem isn't rotating it but triggering it when I rotate the monitor physically
