This high-performance Thunderbolt™ 3 adapter lets you add two 4K HDMI monitors to a computer through a single Thunderbolt 3 port (USB-C™). The Thunderbolt video adapter is compatible with computer systems that support Thunderbolt 3, such as models of Dell™ Precision and Dell XPS. Thunderbolt 3 enables you to use a single port on your laptop to output dual 4K resolution to two independent displays. This performance enables you to run the most resource-demanding applications imaginable on two independent displays. You can output independent content to each display at resolutions of up to 4096 x 2160p @ 30Hz, which is great for editing 4K video or performing other Ultra HD tasks such as creating CAD drawings or reviewing medical imagery.
