This section gives you information about the USB ports available on your monitor.
NOTE: Up to 2 A on USB downstream port (port with battery icon) with BC 1.2
compliance devices; up to 0.9 A on the other 3 USB downstream ports.
Your computer has the following USB ports:
• 1 upstream - bottom

charging capability if the device is BC 1.2 compatible.

mode. If you turn off the monitor and then turn it on, the attached peripherals may take
a few seconds to resume normal functionality.
