Many Surface docks can drive two 4K displays at 60 Hz via USB‑C/Thunderbolt connections. Some models can drive a single 8K display at 30 Hz when both the host device and the display support that resolution.

Power passthrough varies by model and port type: some USB4 docks list up to 65 W of passthrough power, while Thunderbolt 4 docks list up to 96 W.

USB4 and Thunderbolt 4 ports on these docks support data transfer rates up to 40 Gbps, per the product details.

Some docks include a security lock port for physical security and support automatic firmware updates via Windows Update and the Surface app to simplify manageability.

Some Surface dock listings note use of recycled materials—for example, enclosures attributed to 20% ocean‑bound plastic—and state that packaging is about 99% recyclable in OECD countries.

The classic Surface Dock includes two Mini DisplayPorts, one Gigabit Ethernet port, four USB 3.0 ports, and one audio‑out port. It connects to a Surface device using a magnetic Surface Connect cable.
