4. Connect the USB devices.
1. Connect the USB cable between the PC and the monitor (via the upstream USB port).
This upstream USB port transmits data between the PC and the USB devices con-
nected to the monitor. Note that this step is not required if the video source is from
the Thunderbolt™ 3 or USB-C™ inputs.
2. Connect USB devices via other USB ports (downstream) on the monitor. These
downstream USB ports transmit data between the connected USB devices and the
upstream port.
The USB-C™ port on the left or right side works as downstream port and connects with USB devices.
