A user asks a technician why connecting their mobile smartphone to an external monitor using a USB Type-C cable fails to display video, even though the cable fits securely into the port. Which of the following best explains this issue?
- The physical USB Type-C connector shape does not guarantee that the device hardware supports video output protocols.Answer
- BAll physical USB Type-C ports natively support high-speed Thunderbolt video transmission by default specification.
- CThe mobile device must first be configured with Exchange ActiveSync protocols to enable video signals over cable.
- DMobile Application Management (MAM) software must be installed to activate physical video hardware ports on mobile devices.
Answer
The physical USB Type-C connector shape does not guarantee that the device hardware supports video output protocols.
USB Type-C refers strictly to the physical form factor of the port and cable plug. Features such as video output via DisplayPort Alternate Mode or high-speed data via Thunderbolt are optional capabilities that must be specifically designed into the host controller by the mobile device manufacturer.
