The specification allows for USB Type-C cables to be made with no need for extra dongles or converters, and allow compatible devices to output video directly from a USB-C device to a TV display. This means that smartphones, tablets, laptops, cameras, and any other devices with a USB-C port can be built to directly output video to any TV display with a single cable.

Alt Mode, which stands for Alternative Mode, allows non-USB signals to be carried through a USB-C cable. Other USB-C Alt Modes support DisplayPort, MHL, and Thunderbolt. USB-C devices that support these Alt Modes can then, with the correct USB-C cable, transfer those signals in addition to regular USB data.
