Added DDC support for high-end M2 (Pro/Max/Ultra) systems using displays connected via USB-C/ThunderBolt/DisplayPort and HDMI.

(note: somebody with an M2 Pro/Max/Ultra Mac should test it, I am still on M1 :))

…ays connected via USB-C/ThunderBolt/DisplayPort and HDMI.

Could you post a compiled .dmg file so that I can test it?

Sure. This build is unsigned and not notarized so you'll need to manually allow it to run under Security&Privacy. Let me know if you did try it so I can delete this.

@waydabber Awesome work! 😃 Sadly, I was not able to make this work. The volume is not affected when I change the volume slider with the Apple keys or the slider in MonitorControl.

  • LG C2 connected on HDMI_2 (can this affect the logic?)
  • The build has been allowed under Security&Policy>Accessiblity

Can it be related to running Sonoma?

Sadly the LG C2 (as most TVs) does not support DDC. :(

Worked on my new MBP Mac14,9 driving two LG 27UN880-B monitors.

Ah damn. Back to proxy-audio-device for me then 🙂

I am not sure, I can't sign a build for release, it depends on the team. You can of course build a version using XCode anytime.

I thought that project was dead...
I can wait a little more :)

@pakal-org, the project is not dead, just in a bit slow-to-respond mode...

Note: if you don't want to build a release yourself, you can try BetterDisplay meanwhile as it has DDC brightness control for the M2 Pro for free - try https://github.com/waydabber/BetterDisplay/releases/tag/v2.0.6-pre-release

I know about your product :)
I like the "lightness" of Monitor Control ...

Thanks, @waydabber -- this works fine for me on a 14" M2 MBP Mac14,5 and two LG LS27A800U monitors on USB-C cables, after building e038b89.

Maintainers, what blocks generating a new release?

I have compiled it on my own and it works like a charm, very stable so far :)
