Why do I not see any video when using a USB-C to DisplayPort cable?

When connecting to a monitor that accepts a USB-C input, from a docking station that outputs DisplayPort (such as the UD-6950, UD-6950Z, UD-6950H, TBT3-UDZ, TBT3-UDC3), you will need to use a DisplayPort to USB-C "Bi-Directional" cable. This is because many USB-C to DisplayPort cables are unidirectional and only send data in one direction, from USB-C source device to a DisplayPort input port on a monitor.

Additional information:

  • Be sure to use a DisplayPort to USB-C cable that supports the 1.2 DisplayPort standard (or higher). 
  • To ensure optimal performance the maximum recommended cable length should be no longer than 1.8 meters (6 feet).
