Description

Sonnet Tech Thunderbolt Dual HDMI 2.1 Adapter

Key Features

Connects two 4K monitors to one Thunderbolt port: Allows you to connect two 4K @ 60Hz (Mac) or up to 4K @ 120Hz (Windows) HDMI monitors to one Thunderbolt port on your computer.

With 8K@60Hz and Dual 4K@120Hz monitor support: higher resolution and faster refresh rate are supported by some Windows computers. Also supports 1080P and other displays with low resolution @ 60Hz.

Auto Setup, Bus Powered: Sonnet adapter uses operating system drivers and is powered by the Thunderbolt port. Unlike many USB video adapters, Sonnet's model does not use any system resources and therefore does not affect the performance of your computer!

Supports HDMI audio: directs the sound through the connection cable to your screen.

Compatibility: Compatible with Apple M Series Pro/Max/Ultra. Compatible with Intel-based Macs and Windows Thunderbolt computers.
