2.1 What is Type-C Alt Mode?

The Type-C Alt Mode Specification, allows for protocols other than USB to be transferred over a USB connection, such as DisplayPort, HDMI, MHL, or Thunderbolt over the Type-C interface. Alternate Mode can be enabled only through a USB PD protocol handshake through structured vendor-defined messages (VDM) to discover, configure, and to enter or exit Alt Modes. Alternate Modes is highly flexible with multiple high-speed communication lanes and open SBU channels.
