Compact USB-C Dock with 4K HDMI

The StarTech DKT30CHPD3 is a USB-C multiport adapter that adds HDMI 2.0b video at 4K 60Hz, gigabit Ethernet, three USB-A 5Gbps ports and a USB-C port dedicated to 100W power delivery pass-through. It connects through a fixed 12-inch cable and draws up to 12W for its own operation, leaving up to 88W for host charging. The aluminium housing measures 0.50 by 1.80 by 11.80 inches and weighs 0.21 lb.

Ideal for Thin-and-Light Laptops and Tablets

This dock suits users who need a single-cable desk setup for an external monitor, wired network and USB peripherals while keeping the host charged. It works with Windows 7 through 11, macOS 10.9 onward, Chrome OS, iPadOS and Android devices that support DisplayPort Alt Mode. Buyers whose hosts lack DisplayPort Alt Mode over USB-C cannot use the video output or the Ethernet port, and those who require multiple video outputs should consider a larger dock.

Host Must Support DisplayPort 1.4 Alt Mode for 4K

The HDMI port reaches 4K at 60Hz only when the host's USB-C port implements DisplayPort 1.4 Alt Mode; with DisplayPort 1.2 Alt Mode the maximum is 4K at 30Hz. If the host does not advertise Alt Mode video, the adapter will provide data and power only.

Questions about this item

Will the 4K 60Hz HDMI output work on my laptop?

The HDMI 2.0b port delivers 4K at 60Hz when your host supports DisplayPort 1.4 Alt Mode; on hosts limited to DisplayPort 1.2 the same port runs at 4K 30Hz.

What does the 5Gbps USB 3.0 rating actually limit?

The USB 3.0 host link caps total throughput for the three USB-A ports and the USB-C data port at 5Gbps, so simultaneous transfers share that bandwidth.

How much space does the 12-inch attached cable need on my desk?

The dock measures 0.50 by 1.80 by 11.80 inches and weighs 0.21 lb, so the short tether reaches nearby ports without a long cable run.
