Productivity Partner – Expanded Workspace, Enhanced Workflow
Work more efficiently and expand your application desktop space across multiple screens. 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, the Sonnet Thunderbolt Dual HDMI 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.
Go Big, Go Full Screen – Enjoy the Web and Videos at a Distance
Even when you’re not using productivity software, your notebook’s screen can constrain your view. Go big—the Sonnet Thunderbolt Dual HDMI Adapter enables you to connect your computer to your large monitor or big screen TV to browse the web and watch videos on YouTube and other content at a distance.
Not Just for 4K Displays – Supports Full HD (1080p) Displays and Audio Out
While the Sonnet Thunderbolt to Dual 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 full HD 1080p (1920 x 1080) @ 60Hz—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.
Optimal HDMI Video Performance Over Thunderbolt
Sonnet's Thunderbolt Dual HDMI Adapter is compatible with Intel, M1 Pro, M1 Max Mac and Windows 11 or 10 Thunderbolt computers. Thunderbolt's 40Gbps interface lets you run Ultra HD 4K resolution at 60 Hz on both displays at full performance. Got two 4K DisplayPort monitors and looking to connect them through Thunderbolt?
