HP Z32k G3 31.5" 4K HDR Monitor - Manual (Page 19)

Connecting USB devices
Use USB ports to connect devices such as a digital camera, USB keyboard, or USB mouse. There are four USB
ports on the monitor to connect to a device (downstream): three USB Type-A on the rear, and one USB Type-C
and one USB Type-A on the side.
NOTE: You must connect the Thunderbolt cable or USB Type-B cable from the source device (computer) to
the rear of the monitor to enable the USB Type-A ports to serve as a USB hub for a mouse, keyboards,
phones, external hard drives, and practically anything that is USB-connected and can accept 5 V.
