Thunderbolt 3 Docking Station for 4K Monitors

This Kensington docking station connects a notebook to two 4K displays and charges the host with 85 W power delivery. It provides Gigabit Ethernet, dual USB 3.0 ports and 3.5 mm audio jacks in a black and silver chassis. The unit is designed for macOS versions from 10.5 through Sierra 10.12.

Check Host Power Delivery and DisplayPort Support

Before ordering confirm that your notebook accepts charging over its Thunderbolt 3 port and can drive 4096 x 2160 at 60 Hz through DisplayPort. The dock will not charge a host that lacks Power Delivery support. Both displays must connect via the available DisplayPort output for the stated resolution and refresh rate.

VESA Mounting and Daisy-Chain Expandability

Zero Footprint Mounting lets you attach the dock to the back of any VESA-compatible monitor to save desk space. A single Thunderbolt 3 port supports daisy chaining up to five additional Thunderbolt devices. The 2.1 A USB charging port powers a tablet or phone while the system runs.

Questions about this item

What cables and accessories come with the K38239US dock, and do I need to buy a Thunderbolt 3 cable separately?

The package includes the dock and a power adapter; a Thunderbolt 3 cable to connect the host is not included and must be purchased separately.

The specs list two USB 3.0 ports — how do I decide which one to use for a high-draw device?

One USB 3.0 port delivers up to 2.1 A for charging a tablet or phone; use that port for high-draw peripherals and the other for standard data devices.

The headline says 85 W power delivery — what does that actually mean when I plug in my MacBook?

The dock can supply up to 85 W to the host over Thunderbolt 3, so a compatible MacBook will charge while driving two 4096 x 2160 displays at 60 Hz.
