StarTech DK30C2DAGPD USB-C dual DisplayPort multiport adapter with mode switch and 100W Power Delivery passthrough

Product overview

DK30C2DAGPD uses DisplayPort Alt Mode and MST without a display driver. Its physical switch selects dual 1080p with USB 5Gbps, or dual 4K 30Hz with USB 480Mbps; a compatible USB-C power adapter is optional and not included.

Features that matter

Two selectable operating modes

Choose dual 1080p with USB 5Gbps, or dual 4K 30Hz with USB 480Mbps by moving the DP Alt Mode switch.

Single-display 4K 60Hz

A single DisplayPort monitor can run up to 4096 x 2160 or 3840 x 2160 at 60Hz on compatible hardware.

100W Power Delivery passthrough

Accepts up to 100W PD 3.0 from the host power adapter and provides up to 85W to the laptop after the dock reserves 15W.

Portable wired expansion

Adds one USB-A 5Gbps port, one USB-A 480Mbps port and Gigabit Ethernet with an included 1m USB-C cable.

What to know before ordering

Check USB-C capabilities

Full operation requires a host USB-C port supporting DisplayPort Alt Mode; PD passthrough also requires USB PD 2.0 or 3.0.

Dual displays require MST

The host must support MST for two independent displays. MacBook compatibility is limited to one external monitor for this MST adapter.

Power adapter is not included

Use a compatible USB-C power adapter sized for the laptop and dock; up to 15W is reserved for the adapter and attached peripherals.
