ECHO-DK3M-TB Echo Triple 4K Display Dock for Thunderbolt Computers



Echo 13 Triple 4K Display Dock

USB-C Dock with Three DisplayPort Ports, Three HDMI Ports, Gigabit Ethernet Port, Four 5Gbps USB Ports, and 10Gbps USB-C 20W Charging Port

Triple the External Displays Supported – On Computers with Thunderbolt, USB4, or USB-C (with Alt Mode DP) – Including All M1/M2 Series Macs

Apple M1/M2 Mac computers offer outstanding overall performance but have a limit to the number of external displays you can connect to them. If you’re using an M1 or M2 MacBook Air® or MacBook Pro®, that number is one. Featuring DisplayLink™ technology, the Sonnet Echo™ 13 Triple 4K Display Dock beats the limit, enabling you to simultaneously connect three 4K @60Hz DisplayPort or HDMI displays to a single port on your compatible Mac, Windows, and Chromebook computer.

The Triple Advantage – Connect Three 4K Displays Without Compromise

There are several choices in docks that support three displays — don’t choose the wrong one. Some multi-display docks only support slower 30Hz refresh rates, or a 60Hz refresh rate on one display and 30Hz refresh rates on the others. Some offer 4K display support on only one port, while others only offer 1080P (HD) display support. Some include only one type of display connection. Some support only Windows. Echo 13 Triple 4K Display Dock is not some other dock: it simultaneously supports three 4K @60Hz display, HDMI or DisplayPort (DP) or mixed, even when used with an M1 or M2 MacBook Air computer.

Efficiency Booster – Expand Your Applications Workspace

Perfect for use with productivity software such as Microsoft® Office, Echo 13 Triple 4K Display Dock enables you to work more efficiently by expanding your workspace. Whether you need to open multiple applications on their own screens, edit code or view multiple spreadsheets in detail on large displays, or track the stock market, Echo 13 makes it possible.

Plug In – Your Peripherals and Power Your Computer with One Cable

Connect your monitors, USB peripherals, and Ethernet cable to the dock and then link them all to your computer with a single USB-C cable. Got a laptop computer? Echo 13 Triple 4K Display Dock powers it with up to 100W of charging power. When it’s time to leave, just unplug the USB-C cable, grab your computer, and go.

Network Port – Fast Wired Network Connection

Echo 13 Triple 4K Display Dock includes a Gigabit Ethernet port — perfect for connecting your broadband internet directly to your computer without another device competing for bandwidth on your WiFi setup. With the appropriate drivers already installed under macOS, Windows, and ChromeOS, setup is simple.

Powerful 10Gbps USB-C 20W Charging Port

Echo 13 Triple 4K Display Dock features a USB 3.2 Gen 2 (10Gbps) Type-C port up front to support super-fast USB NVMe SSDs at full speed. An added benefit for the port is its support for the USB Type-C Charging spec, enabling the dock to fast-charge your iPhone® or another device even when the computer is sleeping, shutdown, or disconnected.

Handy USB-A Peripheral Connections

Echo 13 Triple 4K Display Dock includes four USB-A ports to connect peripherals such as a thumb drive, USB video camera, printer, and digital camera. Unlike some other docks, Echo 13 doesn’t skimp on power either — each USB-A port can provide 7.5W and is designed to ensure that drives with higher peak power requirements mount without fail.

Not Just for 4K Displays – Supports Full HD Displays Too

While Echo 13 Triple 4K Display Dock supports three monitors at up to 4K resolutions (3840 x 2160) @60Hz, you can also connect monitors with lower resolutions like 1440p or 1080p.

Charge On – Leave the Charger In Your Bag

Connected to your laptop computer with the included 100W rated USB-C cable, Echo 13 Triple 4K Display Dock can provide 100W of power (Power Delivery) from its rear-mounted Computer/Charging port. It can power and charge your computer while connected, even when not in use, allowing you to leave your computer’s power adapter packed away.

Media Reader – Fast UHS-II SD Card Reader

The integrated SD card slot is compatible with SD™, SDHC™, and SDXC™ memory cards, and supports 320MB/s read speeds with UHS-II SDXC cards to quickly offload images and video. In addition, microSD cards are also supported when used with adapters commonly included with the cards.
