@Beurlej The U4320Q only has a single "upstream" USB connection, meaning it can only be connected to a single source system. In order to switch USB peripherals connected to the display between two different source systems, you would need a display with multiple USB upstream data connections. Some Dell displays have this, but not the U4320Q. You might want to look at a USB smart host switch like one of these. They allow you to plug USB peripherals into the switch, and then the switch connects back to multiple source systems. A button on the switch toggles which system can see the peripherals at any given time. Since your camera has a USB-C connector, you would need a female USB-C to male USB-A dongle to connect it to the switch, but those are easy to get. Just make sure you get one actually rated for USB 3.x data. Some only support USB 2.0 and power.
I have the monitor connected to two PC's at once each via HDMI. I was hoping to have the USBC Camera and USBA microphone connected to the monitor (which I can do) and be able to make each PC use the camera/mic in turn. IS this not the case?
@Beurlej If the source PCs only have an HDMI connection to the display, then you won’t be able to use the camera or USB ports at all yet. HDMI is purely a video input. That connection will not carry any USB data from those devices back to the system. If you want to do that, you will need to ALSO connect a USB cable from the display to your system in order to create a USB data path to that system. But this display only has a single USB upstream connection, so it can only have a USB data path to one system at a time. So you can either move that cable back and forth as needed, or look at the USB switch I linked above. You may also want to read the U4320Q user guide available on the Dell Support page to see how to set up USB connectivity.
