add brightness support to non-windows OSes
It's stated in the documentation that color correction and brightness do not work. I'm mostly interested in controlling the birghtness - is display link working on these features for non-windows OSes?

That doesn't solve the problem completely, it's more of a Band-Aid as it does not bring DDC support. Software dimming on LCD panels is nowhere as great as native dimming. -

I use BetterDisplay on Mac to get brightness to work:

It's been over 7.74 years since we've been begging for DDC/CI support with DisplayLink on *nix!
As we wait for a day which may not come, I took action and built my own fix.
It's called HardwareDDC and lets you use a spare HDMI port for DDC/CI VCP codes as another port is used for video from your DisplayLink dock.
I've been working on making it open-source: https://github.com/TeaRex-coder/hardwareddc
and have been sharing about it on Twitter/X for a while: https://twitter.alexandreboutoille.com
I also shared about it on Reddit to gain another perspective on the project: https://www.reddit.com/r/ultrawidemasterrace/comments/1dxoh3b/ddc_fix_on_samsung_g9
Now although it's not a perfect fix, it's better than nothing, right now I'm waiting on receiving the first PCB revision
If you're interested in it, feel free to contact me :)
here's my email: alexandre@boutoille.com

Please add DDC/CI control to macOS; it will be the last missing feature I need.

8'th year running with this feedback gathering and still no feedback from displaylink about this feature? Would also be greatly thankful, I'm using Dell UD22 displaylink based dock with m1 macbook air and been thinking buying 16 inch macbook with 2 display support straight out of hdmi and thunderbolt to control brightness for my dual monitor QHD dell display setup. I have windows pc that connects both monitors straight to rtx and brightness control from keyboard is so needed feature. Room lightning changes so much when its partly sunny weather for ex.

Please provide support for DDC, this would be a great selling point for this software on macOS. This is one of the reasons for going with a Thunderbolt dock instead of a DisplayLink based one.

Please add support for DDC, so contrast of external displays can be adjusted on macOS using monitor control app.
Without this, two external displays driven by DisplayLink look different in their color/brightness/contrast from the one driven by native display engine. -

This is an extremely important workflow that is blocked for macOS users. I have HP G5 and this problem makes this dock station inferior to any other Thunderbolt hub simply due to lack of support of this feature.

This is really a required essential basic feature. I'm so stressed from this blocked workflow, while switching between Windows and MacOS Hardware each day

This issue has been "gathering feedback" for over 6 years. Please implement DDC/CI support on non-Windows OS's.
Thanks

I use Monitor Control to control the brightness of my monitors. I have recently moved from a 2018 MacBook Pro (Intel) to an M2 MacBook Air.
DisplayLink currently does not support DDC/CI on macOS, so MonitorControl has to use a shading layer to adjust the brightness, sub-optimal to say the least. (https://github.com/MonitorControl/MonitorControl/issues/582#issuecomment-917843942)
I would appreciate some focus on this to resolve the issue.

Agree highly needed feature like contrast and brightness on m1

This is highly needed

It would be truly wonderful. Especially DDC control over DysplayLink.

Initial flux support has made my DisplayLink setup usable on macOS. Full DCC/CI support for brightness and source selection would be an amazing next step.

I have sensitive eyes and often change my screen brightness during the day, and since I discovered DDC/CI it has made my life so much more convenient!
And I just bought a QGeeM hub thinking that it would support this but no, as I use Kubuntu on my personal computer and have a MacBook for work. I'd rather plug a separate cable than use the hub and not have DDC/CI, so now I'm thinking of returning the hub because I don't need an expensive one if I don't use it to connect my screen. -

Hello Sirs, could you please at least tell us how many votes & years of asking you need to make this feature work for non Windows users, please? Or at least you're thinking about it/it is on the roadmap or whether it is feasible to achieve at all? What's the purpose of a form to ask for a feature if there's no response? Thank you. (OSX user).

Please add brightness control support for apple silicon.

Please add DDC/CI support. It is stupid that when I connect my dock to my windows laptop, I can control the volume and brightness, but when I connect it to my M1 MacBook Pro it is not working. I see that this issue has been raised more than four years ago, so, I find it unacceptable that in this time you have not managed to implement this easy thing. IT IS CLEARLY A WANTED FEATURE!

Please add DDC/CI support! This is a feature MOST PEOPLE need and after 4 years you still have to implement it.
