Connecting USB devices
USB ports are used 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): two USB Type-A on the rear and two USB
Type-A on the side. There is one USB Type-B port on the rear to act as a hub (upstream).
NOTE: You must connect the 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.
