Quad Display - Up to 4K x 4

When linked to a computer that supports Thunderbolt (or many USB4 machines) the DU4 dock can connect up to four external displays in flexible combinations of the 2x HDMI, 3x DisplayPort and 2x Thunderbolt downstream ports.

The DU4 dock will also connect up to three displays to laptops that don't support Thunderbolt.

Universal All-in-One Connectivity

The DU4 docking station provides universal compatibility and works with all Windows, Mac and Chromebook computers and laptops.

In addition to supporting up to four external displays, the dock provides ample connections for all other standard peripherals including:

  • 2 x Thunderbolt 4 downstream ports (40Gbps / video output capable)
  • 2 x HDMI video outputs
  • 3 x DisplayPort video outputs
  • 1 x USB-C 3.2 Gen 2 (10G)
  • 1 x USB-A 3.2 Gen 2 (10G)
  • 2 x USB-A 3.2 Gen 1 (5G)
  • 2.5 Gigabit Ethernet
  • Combo Headphone/Microphone Jack (384 kHz)
  • SD and Micro SD Card Reader (SD 4.0 / UHS-II - 312Mbps)

Easy Deployment

Allowing all modern USB-C equipped or older USB-A computers to be connected to a minimum of two displays, this dock enables IT professionals and organisations to deploy the DU4 docking station as a single solution across all users.

The DU4 dock helps removes clutter and can power statically assigned workspaces and flexible hot desks in any organisation.

Lock slots allow the dock to be secured when used in shared workspaces.

Power Plus

The dock features a 150W power adapter featuring GaN technology for powerful and efficient operation.

As well as powering the dock and all connected peripheral devices, the dock can provide up to a huge 96W of power to the connected laptop - enough to charge all but the most power hungry machines.
