Two HDMI Displays from a Single USB 3 or Thunderbolt Port

Apple M series 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/M2 MacBook Air, M1/M2 13-inch MacBook Pro, or M3 14-inch MacBook Pro that number is one. Featuring DisplayLink technology, Sonnet USB 3 DisplayLink Dual 4K 60Hz HDMI Adapter beats the limit, enabling you to connect two 4K 60Hz (3840 x 2160); or two 1440p or 1080p 144Hz HDMI displays to a single port on your computer.

Perfect Display Expansion Solution for base M1/M2/M3 Macs

Expand Your Desktop – Connect Two 4K 60Hz or Two 1440p 144Hz HDMI Displays

Not Just for 4K Displays

Supports Full HD (1080p) Displays and Audio Out

While USB 3 DisplayLink Dual 4K 60Hz HDMI Adapter supports two monitors at up to 4K resolutions (3840 x 2160), you can also use it to connect monitors with lower resolutions, 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.

(see Tech Specs for full compatibility info)

USB 3 DisplayLink Dual 4K 60Hz HDMI Adapter is compatible with most computers with USB 3 or USB-C interfaces but is the perfect accessory for M1/M2 MacBook Air, M1/M2 13-inch MacBook Pro, and M3 14-inch MacBook Pro computers, and other computers incapable of natively supporting more than one external display. If your computer otherwise has Thunderbolt 3 or 4 ports, we recommend Sonnet Thunderbolt Dual 4K HDMI 2.1 Adapter.
