Triple 4K docking with 100W power

The IOGEAR GUD3CDHTAA is a USB-C docking station that drives three external displays at 3840 x 2160 resolution. It supplies up to 100W USB Power Delivery to charge the host notebook while providing seven USB ports, gigabit Ethernet and audio connections through a single host cable. A 230W power adapter is included to support the full output.

Suits desk-based multi-monitor setups.

Professionals who need three 4K screens, wired networking and a mix of USB 3.2 Gen 2 and USB 2.0 ports will benefit from the port count and video capacity. Buyers who only need one or two displays, or who rely on bus-powered operation without an external adapter, should consider simpler hubs.

100W USB Power Delivery from a 230W adapter

The dock delivers up to 100W of charging power to the connected laptop, backed by the supplied 230W power supply. If the host device requires more than 100W or uses a proprietary charger that cannot accept USB-C PD, this unit will not meet the power requirement.

Questions about this item

How often will the 230 W power adapter need replacement under normal use?

The 230 W power adapter is a sealed unit with no user-serviceable parts; it typically lasts the life of the dock and only needs replacing if it fails.

Which port hits its bandwidth ceiling first when driving three 3840 x 2160 displays continuously?

The single USB-C 3.2 Gen 2 host link at 10 Gbps is the first bottleneck when all three 4K outputs are active.

How loud and hot does the unit get when all seven USB ports and three 4K displays run all day?

The dock has no fan, so it is silent; the aluminium chassis runs warm but stays within normal operating temperature under full load.
