USB PD DisplayPort™ alternate mode multiplexing

A USB-C port capable of transferring DisplayPort™ signals is either called USB PD DisplayPort or DisplayPort Alternate Mode. DisplayPort Alternate Mode allows you to connect video sources (PCs, Blu-Ray players) and display devices (TVs, monitors) that support DisplayPort to each other through their USB-C ports to broadcast high-definition video. Figure 24 shows a typical block diagram for the signals used in DisplayPort Alternate Mode.

Since a USB-C port can connect to a USB-C or a DisplayPort connector, there are various pin assignments to properly map the physical connection of the DisplayPort main link lanes to the USB-C connector.

A USB-C source side or DFP_D requires assignment C as shown in Table 9, while assignment D in Table 9 is optional. The difference between assignments C and D is that assignment C supports four DisplayPort lanes, while assignment D supports two DisplayPort lanes. A USB-C port to DisplayPort requires assignment E support.

A USB-C sink side or UFP_D requires assignment C as shown in Table 10, while assignment D is optional. The difference between assignments C and D is that assignment C supports four DisplayPort lanes, while assignment D supports two DisplayPort lanes. DisplayPort to USB-C port requires assignment E support.
