U4021QW, firmware M2T105, M2T104, DDPM not working
I installed a U4021QW yesterday and found that DDPM (v1.1.0.0034) is not compatible with the latest firmware M2T105. As a result, the U4021QW is not recognized and I cannot use DDPM with the associated options.
The Mac Mini M2 Pro is connected via Display Port and USB-B to the U4021QW.
The Windows 10 notebook is connected to the monitor via USB-C and DDPM works flawlessly here.
Only on Mac OS does it go wrong and DDPM is not compatible. It says me to enable DDC/CI, check the cable or install the supported firmware.
What's going wrong here?

I find an old DDPM 1.02.0019 and it appears to be working for the time being? Strange that the latest version 1.1.0.0034 is no longer compatible with Mac OS Ventura or Mac Mini M2 Pro?

To clarify,
DDPM (Dell Display and Peripheral Manager) is only for macOS
DDM (Dell Display Manager) is only for Windows OS
The Windows 10 notebook should have DDM 2.1.0.45 installed.
The macOS PC should have DDPM 1.1.0.0033 installed. If macOS DDPM 1.1.0.0033 has issues, uninstall it. Then install macOS DDPM 1.0.2.0019.
macOS DDPM note =

Hello,
Thanks for the additional explanation, which will certainly help others.
In the meantime I have to make do with the old version DDPM 1.0.2.0019
Unfortunately the latest versions 1.1.0.0033 and 1.1.0.0034 are not compatible with Mac Ventura 13.2 en chipset M2?
Does support have any idea when a new update of DDPM (Dell Display and Peripheral Manager) soon for macOS will be released?

Like you, all we can do is periodically check the applicable monitors driver page to see what versions are being offered.
