Two DisplayPort Displays from a Single USB or Thunderbolt Port
Apple^® M1 and 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, Sonnet’s DisplayLink™ Dual DisplayPort Adapter for M1 and M2 Macs beats the limit, enabling you to connect two 4K @ 60Hz or two 1440p @ 144Hz DisplayPort displays to a single port on your computer.

Efficiency Booster

Expand Your Applications Workspace

Perfect for use with productivity software such as Microsoft^® Office, this Sonnet adapter 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 a spreadsheet in detail on a large display, or mirror your notebook’s display on a larger monitor, the Sonnet Thunderbolt AVB Adapter makes it possible.

Go Full Screen

Browse the Web. Watch Videos.

Even when you’re not using productivity software, your notebook’s screen can constrain your view. Go big — the Sonnet Thunderbolt AVB Adapter enables you to connect your computer to your large monitor or big screen TV to browse the web and watch videos on YouTube and other content(1) at a distance.

Connect Three Displays to Your M1 Mac mini

Simple to Set Up and Use

Just download and install the DisplayLink Manager software, connect two displays to the Sonnet adapter, and plug the adapter into your computer. Connect the third display to the Mac mini's built-in HDMI port. Finally, configure settings to extend your desktop on the connected displays. And because your computer powers the Sonnet adapter, there’s no need to connect an additional power supply.

Not Just for 4K Displays

Supports Full HD Displays and Audio Out

While the Sonnet Thunderbolt AVB Adapter supports two monitors at up to 4K resolutions (3840 x 2160), you can also use it to connect monitors with lower resolutions, at higher frame rates, like 1440p or 1080p @ 144Hz — this makes it great for use for different home and work applications. Because audio support is built into the Sonnet adapter, you don’t have to plug in a separate cable to hear sound from connected displays.

Designed for M1 and M2 Macs

Compatible with all Macs (macOS 10.15+) and Windows 11 or 10 Computers

Sonnet's DisplayLink Dual DisplayPort Adapter is ideal for M1 and M2 Macs, and Intel^®-based Mac or Windows computers with USB 3 or USB-C interfaces. Although the adapter is compatible with all Macs running macOS 10.15+ and all PCs running Windows 11 or 10, other than for M1 and M2 Macs, we recommend Sonnet's Thunderbolt Dual DisplayPort Adapter for computers with Thunderbolt 4 or 3 interfaces.
