When the dock is connected to a Windows laptop with a USB4 port, the hub ports will each function as a USB4 port and can be used to connect USB devices and/or a single display. Some USB4 Windows laptops may support dual displays over Thunderbolt if supported by the USB4 Windows Laptop.

Note: the TB4CDOCK is not currently supported on Windows-based **Thunderbolt 3** hosts.
