Portable USB-C multiport adapter

This USB-C multiport adapter adds 4K 60Hz HDMI video, two USB-C 10Gbps ports, one USB-A 10Gbps port and Gigabit Ethernet through a single host connection. It requires a host port with DisplayPort 1.4 Alternate Mode for full 4K 60Hz HDR output and a USB-C power adapter for pass-through charging.

Travellers needing one-cable docking

Users who need a compact dock for hotel desks or hot-desking will appreciate the 12inch attached cable and bus-powered operation for basic data. Buyers whose laptops only support DisplayPort 1.2 Alternate Mode will be limited to 4K 30Hz and should check host specifications first.

DisplayPort 1.4 Alternate Mode requirement

The adapter delivers 4K 60Hz HDMI HDR only when the host USB-C port implements DisplayPort 1.4 Alternate Mode; with DP 1.2 Alternate Mode the maximum is 4K 30Hz. This single host-capability check decides whether the product meets the required resolution and refresh rate.

Questions about this item

What DisplayPort Alternate Mode version is required for 4K 60Hz HDMI output, and what resolution does DP 1.2 limit you to?

The adapter needs a host port with DP 1.4 Alternate Mode to reach 4K at 60Hz. With DP 1.2 Alternate Mode the maximum drops to 4K at 30Hz.

How long is the attached host cable, and what clearance does it add to the setup?

The integrated USB-C host cable measures 12 inches (30 cm), giving extra reach for flexible placement on a desk or in a travel bag.

What must be connected to the USB-C PD pass-through port before the hub can charge the laptop?

A USB-C power adapter has to be plugged into the PD pass-through port; only then does USB Power Delivery pass through to the host.
