How to use

Connect the hub to your laptop using the built-in USB-C cable or compatible USB-C connection. Attach external displays via the HDMI or VGA ports, connect wired network via the RJ-45 port, and plug peripherals into the USB-A or USB 2.0 ports. Ensure your laptop’s USB-C port supports data and video for full functionality; pairing with supported 2018–2019 ThinkPad models can enable additional enterprise features. Actual USB transfer speeds depend on the connected devices and system configuration.

Recommendations

For best performance, connect the hub directly to the laptop’s primary USB-C port that supports DisplayPort Alt Mode and data. When using high-resolution video or large file transfers, verify cable connections and system settings, and consider that real-world transfer rates may be lower than the nominal 5 Gbit/s due to device and environment factors.
