Multi-monitor brightness control is not working

[jess-sys]

Hi,

Thank you for your work !

I tried screenmqtt on a Windows 11 system with two displays with DDC support enabled on both displays.

I was able to turn the displays ON and OFF using the prefix/all/power/command topic.

However, I tried changing the brightness (using prefix//brightness/command, where MODEL is the model field found in the DDC CLI), and nothing is happening.

Do you have any clue ?

Hey, it's cool that this seems useful to someone after all this time 😊

No idea why it doesn't work for you. I also tried v0.4.0 on my PC (I don't use it actively right now) and it didn't work for me either.

But there is possibly good news! I tried compiling the latest commit and that did work for me, so I put it up as v0.4.1.

Let me know if that one works for you!
