Once the device has been recognised and set up by your computer it is ready for use and you can connect other devices as desired such as monitors, USB devices and a network cable. Your laptop will also start charging with up to 100W of power when connected to the dock.
Not all USB-C ports on Windows computers support video output. Ensure that you connect the device to a port that are video capable. Refer to the USB-C Port Video Support section of this manual for further details. Not every USB-C port on notebook computers supports charging. If your computer doesn’t start charging when a power supply is connected to the device and the device is connected to your computer, try a different USB-C port on your machine or consult the computer’s manual to determine which ports accept power from USB PD power sources.

USB-C Port Video Support:
Not all USB-C ports support video output. Many Windows and Chromebook computers have multiple USB-C ports, but only support video output from one or two of them. If using a Windows or Chromebook machine it is important to ensure that you plug the device into a port/ports which supports video output for it to be able to show video on external monitors.
Many USB-C ports that have no labelling support video output, however USB-C ports which have a DisplayPort logo or Intel Thunderbolt logo printed next to them almost certainly support video output and you should look for these icons next to the ports on your computer If in doubt about whether a USB-C port supports video output, consult the user manual for your computer or the support information on the manufacturer’s website. The device can be used with USB-C ports which do not support video output; however you will not be able to connect the HDMI ports to external monitors and show video. The other ports (Ethernet, audio, card readers and USB ports) will be functional.
