U4021QW, macOS DDPM 1.0.2.0017 not working

Dell U4021QW

Dell U4021QW

After updating DDPM to the latest version, it no longer detects my monitor. My monitor is running the latest available firmware M2T104. It is connected via USB-C to a MacBook Pro 16 M1 Pro and it was working fine with DDPM until this update DDC/CI is enabled.

All the links to an older version of DDPM are gone from the Dell.com website so I can't rollback. Does anyone have a link to an older version until these bugs are fixed?

Open the macOS DDPM 1.0.2.0017 --> Settings --> Updates tab. Allow it to update to the October 28, 2022 released macOS DDPM 1.0.2.0019. Restart the Apple PC when done. Then retest.

Same here. It says me to enable DDC/CI, check the cable or install the supported firmware. What the heck, Dell?

Thank you! This worked. Saving to some safe place, until Dell have the DDPM fixed.

Same issue here, I was forced to downgrade to keep it working.

Dell  support said I should contract Apple, but it clearly works when I downgrade....

Thank you very much for that, I was also looking for another version of that DDM release. I installed it, started it and tried to start DDPM in parallel. This looks like it solved the issue of DDPM for now. After I closed both again DPM and DDPM, deleted DPM again. performed a reboot and started just DDPM, it worked as well.

The available macOS DDM and macOS DDPM are listed in the "Dell monitor, Apple FAQ".

* Go back to the top of the Monitors Forum
* Open the Pinned post, "Dell monitor, Apple FAQ"

I confirm the new version works. If you have uninstalled DDPM or you can't open that tab because DDPM doesn't detect the monitor (like @DELL-Chris M specified) download version 1.0.2.19 directly following this link:
