NOTE:
When connecting a display indirectly using a adapter or docking station, it is recommended that you connect the
display to the docking station first, then connect the docking station to the Thunderbolt 3 (USB-C) port on your computer.
NOTE: The devices connected to the ports on the left side of the computer have priority over the ports on the right. While
connecting external displays, it is recommended that you connect the displays to the left ports.
