About Sonnet Thunderbolt 3 Adapter

Workspace Wonder - Thunderbolt Dual HDMI Connections Solution

Connect Two 4K HDMI Displays Using Only One Thunderbolt Port on Your Computer
Do your ideas and workflow need room to grow beyond a single screen? Sonnet Thunderbolt Dual HDMI 2.1 Adapter makes it possible for you to work more efficiently with your laptop, compact desktop or all-in-one computer, enabling you to connect two 4K (3840 x 2160) @ 60Hz displays (Mac) or up to two 4K (3840 x 2160) @ 120Hz displays (Windows) to a single Thunderbolt port on your computer.

Supports Up to 8K Resolution with Windows Computers
This Sonnet adapter can also support one 8K (7680 x 4320) @ 60Hz display plus one 4K @ 60Hz display at the same time - ideal for when you need to connect your computer to the largest displays possible!

Note: The 8K monitor support under Windows depends on the number of monitors, maximum resolution, and refresh rates your computer supports.

Productivity Partner - Expands Your Workspace. Enhances Your Workflow.

Whether you need to edit video or code like a pro, open multiple applications on their own screens, crunch spreadsheets in detail, or mirror your notebook's display on a larger monitor, Sonnet Thunderbolt Dual HDMI 2.1 Adapter makes it possible. Connecting the adapter is plug-and-play easy - your computer powers the Sonnet adapter, so there's no need to connect an additional power supply, and with native macOS and Windows support there's no need to install separate driver software.
