IOGEAR USB-C Triple Display Dock Station GUD3C4K3P 2 in 1 accessory

SKU CH-A4H0-56MHS

Expands a USB-C port into eleven connections with triple 4K 60Hz displays, 100 W charging, four USB-A ports, Gigabit Ethernet and 3.5 mm audio

  • Expand to 11 ports from one USB-C connection
  • Charge laptop and devices with up to 100W pass-through power
  • Drive three 4K 60Hz displays via two HDMI and one DisplayPort
  • Connect four USB-A peripherals for keyboard, mouse, storage and more
  • Add wired Gigabit Ethernet for stable network access

Port expansion

The IOGEAR GUD3C4K3P turns a single USB-C connection into 11 ports so you can attach monitors, storage, audio and a wired network without reaching for the laptop again. It is aimed at professionals who move between a desk setup and mobile work and need every peripheral live at once. The dock adds two HDMI outputs, one DisplayPort, four USB-A sockets, Gigabit Ethernet and a 3.5 mm audio jack.

Triple 4K 60 Hz video

The decisive specification is the ability to drive three external displays at 4K resolution and 60 Hz refresh rate through the two HDMI and one DisplayPort connectors. If your workflow only needs one or two screens, or your laptop GPU cannot output three streams, this dock provides more video bandwidth than you will use. Buyers who need four or more simultaneous displays, or who require higher refresh rates at 4K, should look elsewhere.

100 W pass-through power

Up to 100 W of USB-C Power Delivery passes through the dock to charge the host laptop while all 11 ports are active, so a single cable runs the whole desk. The four USB-A ports share a 5 V bus suitable for keyboards, mice, drives and phone charging, but they do not deliver high-current fast-charge rates for power-hungry tablets. Users whose laptops draw more than 100 W under load will need the original charger instead.

Questions about this item

What does the 100W pass-through mean when I plug this dock into my laptop?

It delivers up to 100 watts of charging power to the connected laptop while the dock is running, so the battery stays topped up during use.

How does the Thunderbolt 3 link limit the three 4K 60Hz video outputs?

The Thunderbolt 3 connection provides enough bandwidth for two HDMI and one DisplayPort output to each run at 4K resolution and 60 Hz simultaneously.

What physical space does the dock need on my desk for its ports and cables?

The unit adds 11 ports — two HDMI, one DisplayPort, four USB-A, Gigabit Ethernet, 3.5 mm audio and the USB-C host connector — so allow room for all attached cables.
