Hi @urmelchen2705

Please fill out the information about your environment so that we can help debug the issue more effectively.
Could you try using https://github.com/waydabber/m1ddc and see if if works in controlling your monitor ?

Also if you are using HDR please try it in SDR mode and if possible with a standard color mode set in the display. I am interested in this display as I was considering buying one so it would be great to know if it works or not. :)

Also, on Lenovo displays you can long press the Exit button (for 10 secs) to enable/disable DDC/CI so that might help. Please don't use HDMI to connect the display to the Mac as that probably won't work.

@waydabber commented on GitHub (Feb 15, 2022):

If DDC is enabled in the display and you get this error then something is wrong with the cable or connection maybe (or this display does not support DDC via the USB-C input - which would be strange as it uses displayport alt mode that carries ddc i2c commands all right). It might be that m1ddc is not fully compatible with the new MBP, I didn't try that. You might want to try a simple USB-C to DisplayPort cable if you have one around to see if it works. You can also try other apps like Lunar (@alin23) and see if that works.

Is the display connected directly via a standard USB-C cable provided by the manufacturer?

Me and @urmelchen2705 have been talking over email. He has already tried Lunar and has the same issue.

The monitor blocks DDC for some reason.

I took a look at the monitor manual and user guide and these are the settings that need to be changed for brightness control to be allowed:

Disable Local Dimming
Disable HDR
Disable Dynamic Contrast
Set Color Mode to Custom
Set Scenario Modes to Panel Native

If those settings are already in that state, then there's nothing we can do to make it work.

I took a look through the monitor database but you seem to be the only one using this monitor with Lunar so far. I have no data on whether the monitor should really support DDC or not. It's possible this is an incompatibility with the M1 DCP (Display Coprocessor) firmware, and hopefully it will be fixed in later updates of macOS.

Oh that's sad as this is a really great display (one that I was considering buying).

But: since this is a FALD/mini-led display, what happens if you use software dimming? If the mini-led control is implemented properly, it should have the same or even superior effect than brightness control via DDC, the hardware backlight should gracefully decrease in intensity while clarity should be retained (somewhat similar to what OLEDs do) so it actually might not make sense to use DDC brightness control anyway. What is your experience with this @urmelchen2705 ? Obviously volume control won't work with DDC being blocked.

Hi @urmelchen2705 - if you enable Avoid gamma table manipulation under Displays in MonitorControl, the app will use the same software technique as QuickShade for dimming. I believe there might be a similar setting in Lunar as well somewhere.
