MST is a feature of the DisplayPort standard, so is available on Displayport, Mini-DisplayPort and DisplayPort over USB-C (USB Alt-Mode) connections. Multi-Stream Transport (MST) is a DisplayPort standard allowing multiple video streams to be sent through a single DisplayPort output on your computer or device. For example, connecting a docking station with two HDMI ports to a Thunderbolt port on a System76 laptop may only activate one HDMI monitor.

Even if the docking station supports multiple video ports, only one at a time could be active. However, depending on the technology used by the dock, there may be only one video stream per port. Many docking stations offer multiple video-out ports on the dock device itself. Be sure you purchase docking stations from a reputable vendor, with a flexible return policy. System76 cannot guarantee that all vendors will follow USB-C or Thunderbolt specs, nor that a manufacturer won't have made hardware or firmware changes since this article was created.
