the DP cable. on page 21 for more information.

If MST connection has been established, make sure you have connected your laptop to the
monitor base using a USB Type-C cable. Otherwise, all the USB ports on the monitor base will
be disabled. You should connect the USB peripherals to the laptop and manage the display
from there.
