"USB C not detected".  Thank you.

Just to clarify, the C3422WE actually has two USB-C ports. The PC has to connect using the provided 1m/3.2ft USB-C to USB-C cable to the C3422WE #5, not #13.

Thank you. I was connecting using the #5 port, but not with the provided cable. Can I use any USB C cable or only the one provided? 

Dell only validates the 1m/3.2ft USB-C cable shipped from the manufacturer.
