Sonnet Technologies announced the USB-C to Dual 4K 60Hz HDMI Adapter, a new addition to the company’s dual-display adapters for Apple M series, Intel Mac computers, and Windows and Chromebook computers. The adapter incorporates a captive cable with a USB-C connector that connects to a compatible computer’s USB or Thunderbolt port for bus-powered operation.

The Sonnet USB-C to Dual 4K 60Hz HDMI Adapter enables users to connect two 4K@60Hz HDMI displays to a single computer port. The Sonnet adapter also includes a USB-C power passthrough port for connecting a laptop computer’s charging cable and passing up to 90 watts of power to the computer for operation and charging.

Many dual-display adapters are incompatible with M series Mac computers, only support lower-resolution displays, or support just one display at a 60Hz refresh rate (the other is limited to 30Hz). The Sonnet USB-C to Dual 4K 60Hz HDMI Adapter supports two 4K — or lower-resolution — displays, operates off power from the host computer’s USB or Thunderbolt port, and is fully compatible with M series and Intel Mac computers, and PCs running Windows 11 or 10 or ChromeOS build R51 or later. Also, most dual-display adapters lack a USB-C power passthrough port.

The Sonnet USB-C to Dual 4K 60Hz HDMI Adapter (part number USBC-DHDMI) is $99.99.
