DDC support for high-end M2 (Pro/Max/Ultra) systems

[waydabber]

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 :))

[JerryZhangZZY]

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

[waydabber]

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.

DDC works perfectly on M2 Pro, nicely done mate!

[waydabber]

Great! Thanks for the feedback!

Amazing! DDC works sweetly fine on M2 Ultra. Awesome job, dude! 🤩

@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 🙂

🙌 LGTM ! Thank you so much for the PR, everything looks good as far as I can see !

[waydabber]

Thanks @the0neyouseek ! :)

Can we expect a release soon ?

Thanks

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 :)

[waydabber]

@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

[pakal-org]

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

[waydabber]

Yes, I can understand that. :)

What a flex! Fixing the competition's issues 😆 Great work, @waydabber 😘

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?

[JoniVR]

We'll do a new release with this fix soon.

[kaeferfreund]

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

[lestmak]

On a Mac Mini M2 Pro with an LG UltraWide Monitor 38WN95C-W. Working beautifully and perfectly. Thanks for this!

[frunika]

Work's perfect. Thanks! :)
