Overview
Connecting two ultra high definition monitors to a MacBook that normally supports only one is the main job of this Kensington dock, which uses DisplayLink to add screens over USB. One cable also charges the laptop and links Ethernet, audio and six USB ports.
Dual screens for any MacBook, including base M-series models, solve a common limitation in one box. DisplayLink video depends on the host computer's software, unlike native docks.
Who it's for
Office and hybrid workers with MacBooks, Surface or Windows laptops get two screens and charging from one cable. Gamers and video editors should look at a native Thunderbolt dock.
Pros and cons
- Two 4K screens on any MacBook
- Laptop charging up to 85W
- Mix of HDMI and DisplayPort
- Six USB ports
- Relies on DisplayLink video
- Thunderbolt runs at USB-C speeds
- Lock sold separately
- USB-A laptops need a splitter to charge
Performance notes
Extra displays run through DisplayLink compression over USB, which suits office work and video playback. Laptop charging tops out at the rated power delivery, with the rest of the adapter budget going to peripherals.
