The ARC-8050T3U series are equipped with dual Thunderbolt 3 ports for connecting to any Thunderbolt 3-enabled host and offers an additional Thunderbolt 3 port for daisy-chaining other peripherals, while also supplying power for quick notebook charging. The ARC-8050T3U also sports a full sized DisplayPort 1.4 video output on its rear, allowing for a quick and easy 8K 30Hz display setup.

If an ARC-8050T3U is plugged in a USB-C (or) USB X.X computer port, a USB device controller inside the ARC-8050T3U-enabled system is activated, and the inside USB device controller drives USB (2.0, USB 3.2 Gen 1, or USB 3.2 Gen 2) signals to the USB-C port. In this condition, the ARC-8050T3U Thunderbolt 3 port behaves exactly like a typical USB-C 3.2 Gen 2-enabled connector.
