Why can't windows and macos adjust monitor brightness natively via dDC?
Why do they not allow doing the same for external monitors using DDC? There are several apps that do just that.

Making the "xrandr --setmonitor" setting permanent
If I were you, I would take a look at ddccontrol. It's a utility that allows you to query the state and send commands to your monitor via the command line. I currently use it to increase / decrease the brightness of my monitor depending on the time of day.

Automatic Desktop Monitor Brightness Adjustment
Before I look into automating it, I wanted to get it working first. For this, I have a tool called ddccontrol (https://github.com/ddccontrol/ddccontrol). But this needs root privileges. So I'm just wondering if there are other ways, since I couldn't find any.

Arduino project - Swapping between monitor inputs
I wouldn't do it that way; opening and soldering in the monitor. I'd go with using DDC and VCP, just hook i2c and GND to the unused VGA port and then use something like this to send a custom VCP command (I think it's 60 to switch).

Ask HN: Monitor with physical dials for brightness/contrast?
Yes, in my experience, most monitors do accept DDC commands even if the video signal comes from another input as long as the other input keeps the line busy.
For example, on the Pi this was not possible in past, we had to wait for the vc4-kms-v3d GPU driver to get this functionality. Thankfully it’s beta version coincided with the M1 release :)
There’s no DDC dial available, but it’s something I tried doing in the past using an ESP32 that gets Power-over-HDMI [1] and sends DDC through the I2C wires of the HDMI cable [2]
Unfortunately I had to put that on hold as I started a Mac app studio [3] which took most of my time away. (and I also realized I don’t have the means to sell and distribute a hardware project)
