Work Efficiently
Display with Apps Windows IconWhether you need to view your work on a large UHD display or across two displays, or you need to view it with the highest resolution possible, this Sonnet plug-and-play adapter enables you to work more efficiently. With two displays attached, you can fill one with full-screen workspace, and use the other for tools, other applications, and more.

Convenient – No External Power Adapter Required
To use it, simply plug in the Sonnet Thunderbolt 3 to Dual DisplayPort Adapter into one of your computer’s Thunderbolt 3 ports, and connect DisplayPort cables (sold separately) between the adapter and your monitors. Your computer powers the Sonnet adapter, so there’s no need to connect an additional power adapter.

Capable
Thunderbolt Certified for Mac® and Windows®(2), the Sonnet Thunderbolt 3-to-Dual DisplayPort Adapter can be used with the latest and best computers available. If you need to connect a monitor without a DisplayPort (DP) input, the Sonnet dual DisplayPort adapter is compatible with active DP-to-HDMI, DP-to-DVI, and DP-to-VGA adapters. And, unlike USB adapters, the Sonnet adapter won’t drain system resources that might impact your computer’s performance.
