Suits users with Thunderbolt 4 laptops needing
The dock requires a host system with a Thunderbolt 4 interface to deliver its full video and data bandwidth. It is not for users whose computers only offer USB-C or USB 3.x ports without Thunderbolt certification. Buyers needing legacy video outputs such as VGA or DVI must use separate adapters. Those requiring more than six USB ports should consider a larger hub.
Single Thunderbolt 4 upstream port drives four
The upstream Thunderbolt 4 connection carries all video, data and Ethernet traffic to the host. It enables the four-display maximum and the 2.5GbE network link simultaneously. If the host port is limited to Thunderbolt 3 or USB4 without full bandwidth, the display count or network speed may be reduced. Verify host specifications before purchase.
