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.
* The available number of outputs and maximum resolutions are dependent on the capabilities of the computer used with the docking station. Refer to the resolution support table for full details on the output capabilities of computers based on their specifications.
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 storage, networking, audio, SD cards and a host of USB accessories.
Lightning Fast File Transfer
With the 40GBps speed of Thunderbolt 4, this dock allows you to take advantage of high-end external SSD and SD card transfer speeds when moving large files.
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.
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, clutter-free solution across all users and hot desks, complete with lock slots for shared workplaces.
*Requires a USB-C to A adapter or cable - available separately.
General
Note: When connected to a USB-A port, only HDMI 2 and 3 can be used (2x 1920*1080@60Hz displays).
Maximum resolutions for the different video outputs vary depending on the capabilities of the connected computer. Guidance on achievable resolutions can be found in the resolution support table in the specifications for the product.
The device supports USB PD 2.0 and 3.0 power adapters up to 100W. Note that the device can reserve up to 15W from power adapters to power itself and peripheral devices connected to the ports on the hub so it is best to use a USB PD power adapter that is at least 15W larger than the power adapter that was supplied with the computer.
The maximum Wattage that this hub can provide to charge a computer is 85W (100W power adapter minus 15W reserved by the hub). This is sufficient for most laptops, but a few larger high performance laptops may slow charge or not be able to charge through this device. If the computer shows a message indicating that it is not receiving enough power from the device, increase the size (Wattage) of the connected power adapter or connect the power adapter directly to the computer.
