Dual 4K Docking Station

The Maxtek MX-DS-U3901 is a USB 3.1 Gen 2 docking station that drives two 4K displays through HDMI and DisplayPort outputs. It provides four USB-A ports, one USB-C port, Gigabit Ethernet, audio in/out and a Kensington lock slot, all powered by a 150W adapter.

Suits laptops with a video-capable USB-C port

This dock serves users who need dual 4K monitors, wired networking and extra USB peripherals from a single cable. It does not suit laptops that lack a video-capable USB-C connection or setups that require more than four USB-A ports.

Dual 4K video over USB 3.1 Gen 2

The decisive spec is the ability to run two 4K displays simultaneously over a USB 3.1 Gen 2 (10Gbps) host link. If the host port only supports data or a lower video mode, the second monitor will not activate.

Questions about this item

Does my laptop need a USB-C port with DisplayPort Alt Mode to drive two 4K monitors from this dock?

Yes, the host must provide USB-C video-out (DisplayPort Alt Mode) so the dock can split the signal to its HDMI and DisplayPort outputs for dual 4K.

Will my older USB 3.0 flash drives and mouse run at full speed on the three USB 3.1 Gen 1 ports?

They will work at their native USB 3.0 / 3.1 Gen 1 rate of 5 Gbps, which matches the three downstream USB-A ports on the dock.

How can I confirm the 150 W power adapter is delivering 20 V / 5 A to charge my laptop while the dock is running?

Check the laptop's battery indicator for the charging icon and verify the power brick's label reads 20 V / 5 A; the dock passes that PD profile through its upstream USB-C connection.
