How to connect dual, up to 4K monitors at up to 4096 x 2160, 30-bit colour at 60Hz

(Tested with LG 34UC98 and an HP z34c – both 21:9, 3440 x 1440 panels with DisplayPort 1.2 and HDMI 2.0)

The first monitor connects to the dock’s DisplayPort. The second uses a USB-C/Thunderbolt 3 cable to a Thunderbolt 3 compatible monitor.

Or use a USB-A 3.0 to DisplayPort 4K adaptor that works well from any of the dock’s USB-A ports but adds $106.99 plus freight to the cost.

Thunderbolt 3


Ethernet was a rock solid 1Gb/s.

It was difficult to test the 40Gb/s (5,000 MB/s) Thunderbolt 3 claim. Attaching a Samsung T3, 1TB, SSD drive gave an amazing and consistent write speed of 400MB/s (the theoretical maximum rate is 450MB/s), so all I can surmise is that the port is very fast.

One USB-A port supports 5V/2.1A sleep charging and two support 5V/1.5A

GadgetGuy’s take – Belkin Thunderbolt 3 Dock for Mac

I have tested many docks over the years, and apart from odd driver issues that are usually promptly fixed they all work flawlessly.

I have been testing various Thunderbolt powered and unpowered docks on both Mac and Windows. This works well on Mac.


• Worked flawlessly with MacBook
• 1m cable is very convenient but provides maximum 60W/20Gb/s
• Provides 85W power upstream with a .5m cable (not supplied)
• Well built, Belkin quality and support


• Very large 170W power brick weighs as much as the dock
• Would have liked an HDMI port but realise the Thunderbolt 3 standard does not support this
• Need to supply a .5m cable as well
• No Apple specific ports link Thunderbolt 2, S/PDIF digital audio port, Firewire 800 or Lightning


As a MacBook dock.

Overall: 4 out of 5
Features: 4 out of 5 – No Apple specific ports
Value for money: 4 out of 5 – about the same cost as other docks
Performance: 4 out of 5 – in all tests it met specifications
Ease of Use: 4 out of 5 – The 1m cable is convenient but confusing
Design: 4 out of 5 – Brushed aluminium
