Man Working Behind Two 4K Monitors
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.

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.
