  When it is the display source (DFP_D)
  When USB Type-C is the display source (DFP_D), the pins A2-A3, A8, A10-A11 and B2-B3, B8, B10-B11 of TYPE-C will be configured as A, B, C, D ,E,F.
  The A, B, C and D pins are used with USB Type-C cables as well as USB adapters to use Type-C with other video standards such as VGA, DVI and HDMI.
  The E and F pins are for the DisplayPort adapter plug or socket.
  DisplayPort can use two or four of the USB-C differential high-speed channels ML0, ML1, ML2, and ML3 for payload data transmission, and pins A8 and B8 are used for DisplayPort AUX channel sideband (SBU) signal routing.

  When used as a display receiver (UFP_D)
  When USB Type-C acts as a display receiver (UFP_D), pin assignments A, B, C, D, and E are configured for USB.
USB Type-C cables
  In both cases (DFP and UFP), the video data rate will vary depending on the configuration.
  A USB Type-C receptacle that supports DFP_D functionality (the receptacle can be used as a DisplayPort source device or as a DFP_D on a DisplayPort breakout device) should support one or more DFP_D pin assignments.
  Likewise, USB Type-C receptacles that support UFP_D (the receptacle can act as a DisplayPort sink device or as UFP_D on a DisplayPort breakout device) should support one or more UFP_D pinouts.
