Sonnet’s Thunderbolt™ Dual DisplayPort Adapter is certified for use with both Mac® and Windows® Thunderbolt equipped computers, and enables you to connect two displays to a single Thunderbolt port on your computer. With the adapter connected, you can connect two 4K @ 60Hz DisplayPort monitors, or two 1440p @ 144Hz monitors.

Work Efficiently

Whether you need to view your work 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 Dual DisplayPort Adapter into one of your computer’s Thunderbolt 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.


Thunderbolt Certified for Mac® and Windows®, the Sonnet Thunderbolt 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.
