Run the most resource-demanding applications on two 4K 60Hz displays, using your Mac or PC

This high-performance Thunderbolt™ 3 adapter lets you add two 4K 60Hz HDMI monitors to your Windows® or Mac computer through a single Thunderbolt port.

The Thunderbolt video adapter is compatible with computer systems that support Thunderbolt such as models of MacBook Pro, Dell™ Precision and Dell XPS. Thunderbolt is a protocol that uses the USB-C™ connector, but your computer system must support Thunderbolt in order for the adapter to function as expected. If you connect the adapter to a USB-C port that does not support Thunderbolt, the adapter will not function.

Connect two UHD 4K displays to your computer at 60Hz

With an unprecedented 40Gbps of throughput, Thunderbolt 3 enables you to achieve the previously impossible feat of using a single port on your laptop to output dual 4K resolution at 60Hz to two independent displays. This performance lets you run the most resource-demanding applications imaginable. You can output independent content to each display at resolutions of up to 4096 x 2160p (60Hz), which is perfect for editing 4K video or performing other Ultra HD tasks such as creating CAD drawings or reviewing medical imagery.

Supports dual 4K displays to work more efficiently

Functioning as an external 2-port graphics adapter with audio support, this is a compact and convenient alternative to a laptop dock when you don’t need full docking capability.

With two UHD 4K displays, you can work more efficiently from your laptop, so you can accomplish more in the same amount of time. With each display delivering 4K performance, you can have four times the screen space compared to 1080p. Creative professionals can be more productive with the freedom to edit 4K video on one display while previewing raw video playback on the second 4K display.

Won't drain system resources

This adapter helps to keep your system running at peak performance. Unlike USB external video solutions, Thunderbolt 3 lets you run Ultra HD 4K resolution at 60Hz on both displays without draining system resources.

Because it’s backward compatible with your high-definition 1080p displays, this is a great accessory for home, office or other desktop workspace applications.

Your computer’s Thunderbolt ports might not function properly until you update one or more of the following on your computer:

• BIOS
• Thunderbolt firmware
• Thunderbolt 3 controller drivers
• Thunderbolt 3 software

The required updates will vary depending on your computer.

For an up-to-date list of affected computers and instructions, visit http://thunderbolttechnology.net/updates. If your manufacturer isn’t listed on the Thunderbolt website, contact your manufacturer.

Note: In order to connect to two displays at 4K 60Hz, your computer system must have a fully enabled Thunderbolt port that supports up to 40Gbps or the host must support dual displays over Thunderbolt.
