U3818DW, DDPM 2.0.2.11 does not work

I am reaching out for assistance with an issue regarding my Dell U3818DW monitor. Unfortunately, the monitor does not work with the Dell Display and Peripheral Manager (DDPM) version 2.0.2.11.

My setup includes a Dell WD19S docking station through which the monitor is connected. However, the monitor does not appear in the DDPM. I have also tried connecting the monitor directly with a USB-C cable, but unfortunately, this was also unsuccessful.

I would greatly appreciate any support or suggestions you can offer.

Thank you in advance for your help!

Best regards,

Marcel
