Microsoft Surface USB4 Dock Wired Black USB4 Connectivity 1000 Mbit/s

The Microsoft Surface USB4 Dock Wired Black is a compact wired docking solution that uses USB4 connectivity to expand the capabilities of compatible laptops and tablets. It provides a stable wired connection with a Gigabit Ethernet port delivering up to 1000 Mbit/s, a single HDMI output, and a USB 3.2 Gen 2 Type-A port for peripheral devices. The dock accepts power via a USB Type-C connector and supports a 100 W power supply, with up to 65 W available for passthrough charging to connected host devices. Its slim housing (120 mm × 60 mm × 15 mm) and integrated Kensington cable lock slot enable secure, space-saving deployment on desks and in shared workspaces.

Advantages

The dock combines USB4 high-speed data capabilities with backward-compatible USB-C support, enabling fast data transfer and reduced latency for connected devices. By providing a dedicated Gigabit Ethernet port it ensures reliable network access compared with wireless connections. The included HDMI port and support for dual 4K displays (at up to 60 Hz where supported by the host and displays) expand visual workspace. A compact form factor and a Kensington lock slot add practical security and ease of placement in both personal and professional setups.
