Sonnet's new dock lets M1 Mac owners have three 4K displays

Sonnet's Echo 13 Triple 4K Display Dock offers three-screen support for a M1 Mac, with it also providing legacy ports too.

Introduced on Monday, the Sonnet Echo 13 Triple 4K Display Dock follows on from the Echo 11 and Echo 20 as ways to add more ports to your Mac or MacBook Pro. As the name indicates, its main feature relates to how many displays it can handle.

On the back of the dock are a trio of port pairs, with three each of DisplayPort and HDMI connections on offer. As they are paired, users can select which port from each pair to connect to, depending on their needs.

For owners of M1 and M2 Macs that have to deal with support for a low number of displays, the inclusion of DisplayLink means those limited Macs can work with more displays than Apple's limit. That means even an M1 MacBook Air with built-in support for one external display can now go up to three.

The dock can support up to three 4K displays at up to 60Hz, and they can be mixed between the HDMI and DisplayPort connections.

The port selection at the back includes four USB 3.2 Gen 1 Type-A ports, a gigabit Ethernet port, and a USB-C connection to the host computer that can also handle 100W of power delivery.

At the front is another USB 3.2 Gen 2 Type-C charging port that offers 20 Watts, separate headphone and microphone jacks, and a fast UHS-II SD card slot.

The Echo 13 Triple 4K Display Dock is available now from Sonnet, priced at $239.99.
