The dock can upstream 85W (USB-C PD 2.0 5-20V/4.25A) that means it supports 15-inch MacBooks and 15/15.6-inch Windows 10 laptops. It can downstream data and power to devices – we are not sure if it supports 85W – but we suspect so.

The four rear USB-A 3.0 – ports support 5V/.9A each – not fast charge. Two of these have sleep charging. These are fine for most external backup to flash, SSD or HDD.

You can connect up to five daisy-chained devices to the downstream Thunderbolt 3 (one device to the next).

Notebooks – all welcome

By chance, I had the one notebook that does not work well with the LD5400T – a Huawei MateBook X Pro with almost no bottom bezel.

You see the security arms partially obscure the bottom taskbar where most laptops have a bezel. It is not a big issue.

It allowed the full-screen tilt back to 135°. We tried a Lenovo Yoga 920 360° hinge, and it could go to about 160°. We tried with a MacBook 15 and it was fine.

The laptops sat nicely with no keyboard platform tilt.



DisplayPort 1.2 supports a 5K (5120 x 2880 @ 60Hz) or a 4K (4096 x 2160 @ 60 Hz) with a second 4K via DisplayPort over USB-C.

We tested with a range of 32 to 42-inch 4K monitors, and it was perfect firing up the second monitor as soon as the laptop work up – that does not always happen with cheaper docks.

There is also a 3.5mm combo audio and a 1 Gigabit Ethernet port (See DockWorks for added functionality)


Ethernet was rock solid at 1GBps.

Using the Samsung Thunderbolt 3 X5 PCIe NVME SSD 1TB we achieved 2600/1500 MBps sequential read and write – about the same as the SD5200DT dock.


For sysadmins

  • WiFi Auto Switch allows the dock to prioritise LAN (Ethernet) over WiFi when you dock. When you undock, the laptop will resume using Wi-Fi.
  • MAC Address Passthrough allows the docking station to mirror the Laptop’s MAC ID. When you undock the laptop, the dock resets to its default MAC ID.
  • Fob management

GadgetGuy’s take – Kensington is a safe bet for Mac and Windows

I have tested a lot of Thunderbolt 3 docs. Twelve months ago they were in their infancy, and Kensington is the only one that performed well out of the box.

Since then Intel has rolled-out several Thunderbolt 3 software updates and computers have advanced so that everything just works.
