Portable dual 4K workstation dock

This StarTech DK30C2DAGPD adapter connects a Windows USB-C laptop to two DisplayPort monitors, a Gigabit Ethernet network and two USB-A peripherals while delivering up to 85W of charging power through its 100W Power Delivery 3.0 pass-through port. It is built for mobile professionals who need a compact, single-cable desk setup.

Fanless aluminium chassis runs silent

The 0.70" x 2.40" x 4.70" enclosure weighs 7.10 oz and uses passive cooling, so it adds no audible noise to a quiet office. Power draw scales with the attached laptop and peripherals, peaking at the 100W PD 3.0 input limit when the host demands full 85W charging plus bus power for the downstream ports.

One USB-C host port required

A host system must provide a USB-C connector with DisplayPort Alt Mode and Power Delivery sink capability to drive both video streams and accept charge. The adapter supplies two DisplayPort outputs configurable as dual 4K 30Hz, dual 2K 60Hz or single 4K 60Hz via the DP Alt Mode switch, plus one USB 3.0 Type-A and one USB 2.0 Type-A port for legacy accessories.

Questions about this item

How do I install the DK30C2DAGPD and which step is often missed?

Connect the USB-C male plug to the laptop, attach an external USB-C PD 3.0 power adapter to the female PD port for 85W laptop charging, then plug DisplayPort cables into the two 20-pin outputs; the step often missed is setting the DP Alt Mode switch for the desired resolution and USB speed before connecting monitors.

What maintenance or replacement will the DK30C2DAGPD need later?

No scheduled maintenance is required; keep the RJ-45 and USB-A ports free of dust, ensure the USB-C PD power adapter remains functional for 100W PD 3.0 pass-through, and replace only if a port or the DP Alt Mode switch fails.

What limit appears first under sustained use of the DK30C2DAGPD?

The video modes cap at dual 4K 30Hz, dual 2K 60Hz or single 4K 60Hz, USB data is limited to one USB 3.0 and one USB 2.0 port, and laptop charging stops at 85W even with a 100W PD 3.0 source.
