Triple-Monitor USB-C Dock

This universal USB-C dock adds ten ports to a Windows laptop, Chromebook, MacBook Pro or smartphone through a single USB-C or Thunderbolt 3 connection. It provides HDMI, dual DisplayPort, Gigabit Ethernet, three USB 3.2 Gen 2 Type-A ports, a USB-C data port, USB-C Power Delivery charging and a 3.5 mm headphone jack. No special drivers are required when the host supports USB DisplayPort Alternate Mode.

Three 4K Outputs with Scaling Limits

Each video output supports a single 4K monitor at 3840 x 2160 and 60 Hz with 2.1-channel surround sound and HDCP 2.2 compliance. The dock extends a 1080p desktop across two screens at 60 Hz and across three screens at 30 Hz. 4:4:4 chroma subsampling is supported for colour-critical work. Systems without DisplayPort Alt Mode cannot use the video outputs.

Pass-Through Charging Up to 85 W

The USB-C Power Delivery 3.0 port accepts up to 20 V at 4.25 A (85 W) to charge a connected PD-compliant laptop, tablet or phone while the dock is in use. A Gigabit Ethernet port delivers wired 10/100/1000 Mbps network access when Wi-Fi is unavailable or a stable link is preferred. The dock draws power from the host’s USB-C supply, so total system power depends on the attached charger.

Questions about this item

Will this dock run three external monitors from my laptop's single USB-C port?

Yes, the HDMI and two DisplayPort outputs each support 4K at 60 Hz on a single screen, and the dock can extend a 1080p desktop across three displays at 30 Hz.

How can I verify the dock is delivering video at the full 4K 60 Hz rate after I connect it?

Check the display settings on your Windows or Mac system; each monitor should report 3840 x 2160 at 60 Hz, and the HDCP 2.2 handshake will allow protected 4K streaming without errors.

Does the package include the host cable and power supply, or do I need to buy them separately?

The dock ships with a detachable USB-C host cable; the 85 W Power Delivery input uses your laptop's own USB-C charger, so no separate power brick is required.
