This high-performance Thunderbolt 3 adapter lets you add two 4K 60 Hz DisplayPort monitors to a computer through a single Thunderbolt 3 port (USB-C), or it can be used to connect your Thunderbolt 3 port to a 5K 60 Hz display using two DP cables. The Thunderbolt video adapter is compatible with computer systems that support Thunderbolt 3, such as models of Dell Precision and Dell XPS.
Your computer’s Thunderbolt 3 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.

Note:
If you're using a video adapter to connect this device to a monitor other than DisplayPort, such as HDMI or VGA, an active video adapter is required.
In order to connect to two displays at 4K 60Hz, your computer system must have a fully enabled Thunderbolt 3 port that supports up to 40Gbps or the host must support dual displays over Thunderbolt 3.
