Figure 13 illustrates a USB Type-C to DisplayPort (4-lane) adapter application, which enables connectivity between a PC that supports

a Type-C port with DisplayPort Alternate Mode support and a legacy monitor that has a DisplayPort interface.

The application meets the requirements described in Section 4.2 of the VESA DisplayPort Alt Mode on USB Type-C Standard Version

1.0 (Scenarios 2a and 2b USB Type-C to DisplayPort Cables).
