U4323QE, USB 3.0 problems
I recently purchased a Dell u4323qe monitor. I am using it with a latitude 5530 and a Dell WB7022 4k web camera. I have connected the laptop to the monitor using the provided USB-C to C cable to the USB-C 1 port on the monitor. Ethernet cable is attached to the monitor. Monitor is set to 3480x2160 resolution at 60 hz. Everything works just fine without need for my separate thunderbolt docking station, except when I go to plug in the WB7022 camera to the USB 3.2 port on rear of monitor. When I do this, the Dell peripheral manager tells me the camera cannot operate in 4k mode or do AI framing unless the camera is connected to a USB 3 port. The ports in the monitor are supposedly USB 3.2 ports, so this seems like it should work, but it does not. Any suggestions?

Online U4323QE User's Guide page 53 =
USB-C Prioritization =
Allows you to specify the priority to transfer the data with high resolution (High Resolution) or high speed (High Data Speed) when using the USB-C port.
Test the three blue USB 3.2 Gen 2 ports after changing USB-C Prioritization to High Data Speed.

A few other items of note to add to the above:

I will also note that if I connect my laptop to my Thunderbolt docking station and then connect the thunderbolt docking station to the u4323qe monitor using the provided USB-C to C cable and using the USB-C Display Port connector on the docking station and the USB-C 1 (which is the USB-C 90W DisplayPort connector), and then plug the camera into one of the docking station's USB-A ports, it works just fine.
Also, if I plug the camera directly into the USB-A port on the latitude 5530, the camera also works just fine.

Re: Any suggestions?
While everything is connected to the monitor, disconnect and reconnect the USB upstream cable. Check to see if USB devices have re-established to USB 3 performance.

@DELL-Chris M , this did the trick! Thank you so much. When I changed this setting and disconnected the USB-C Cable and then reconnected, the OSD shows USB 3.1. When I disconnected the camera and reconnected, it now works without showing error message.
