How to use

Connect the dock to a laptop USB-C port using the integrated Type-C cable. If you need to power the laptop while using the dock, attach a compatible USB-C power adapter that supports Power Delivery to the laptop or to the dock if applicable. Plug an HDMI cable from the dock to an external monitor to enable external display output; set the display mode in the operating system if necessary. Connect Ethernet, USB drives, keyboard or mouse to the corresponding ports; the operating system should detect standard devices automatically. For optimal performance, use USB 3.0/3.1/3.2 cables and a power adapter that can supply sufficient wattage for your laptop model.

Recommendations

Use a Power Delivery charger rated at or above the laptop’s required wattage to maintain battery charging while the dock is in use. For 4K video output, use a high-quality HDMI cable and ensure the connected laptop and operating system support the desired resolution and refresh rate. If network performance is critical, verify the Ethernet link speed and use a reliable network cable and switch.
