How can I control screen brightness from my m1 max? Willing to pay for a solution.
It’s free for manual brightness adjustments.
Just make sure to use one of the Thunderbolt ports of the MacBook.
And if it still doesn’t work, check if there’s any monitor setting that could block DDC by going through this FAQ: https://lunar.fyi/faq#brightness-not-changing
All we can do is to provide software dimming using Gamma table alteration, or tell people to use the Thunderbolt ports instead.
I had found something on stackexchange to do this for previous gen macs, but was unable to replicate for current gen. This is something I would be willing to pay for. https://apple.stackexchange.com/a/179204
I figure with the HDR display there must be a way to control the actual backlight brightness.
The app only supports integer values between 0 and 100 but the framework supports floating point values between 0 and 1.
You can try installing Lunar’s CLI (https://lunar.fyi/#cli) and then running something like the following in a terminal:
lunar display-services SetBrightness builtin 0.005
If you don’t see much difference between 1% and sub-1% values then there’s no way to dim the backlight further, and the only remaining method would be Gamma dimming which Lunar can do if you disable the Apple Native protocol from the Controls menu.
