Connect Two 4K 60Hz HDMI Displays via a Single Thunderbolt or USB-C Port

It’s well known that Apple® M series Mac® computers offer outstanding performance but limit 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, the bus-powered Sonnet USB-C to Dual 4K 60Hz HDMI Adapter beats the limit, enabling you to connect two 4K (3840 x 2160) @ 60Hz; or two 1440p or 1080p @ 144Hz HDMI displays to a single port on your computer.

Perfect Display Expansion Solution for M1/M2 Macs

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

Features DisplayLink Technology – Connect via a Thunderbolt or USB Port

Power Passthrough

Charge Your Computer at the Same Time

M1 MacBook Air, and M1/M2 13-inch MacBook Pro computers — and some PC laptops — do not include dedicated power ports. With the limited ports available, you have a choice; connect the USB-C power cable to a dual-purpose USB-C or Thunderbolt port, or connect an accessory instead. Although it is bus-powered when no USB-C power adapter is connected, the Sonnet USB-C to Dual 4K 60Hz HDMI Adapter enables you connect two HDMI displays and power your computer through the same port. Simply connect the Sonnet adapter to your computer, and then plug in the USB-C power cable into the Sonnet adapter — up to 90W of power passes through the adapter to your computer using the same cable as for connecting two HDMI displays. Problem solved!

The Sonnet USB-C to Dual 4K 60Hz HDMI Adapter is compatible with most computers with USB-C interfaces but was designed 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 4 or 3 ports, we recommend Thunderbolt to Dual 4K HDMI 2.1 Adapter instead.
