The HDMI alternate mode lets a user connect the reversible USB-C connector with the HDMI source devices (mobile, tablet, laptop). This cable connects to video display/sink devices using any of the native HDMI connectors. This is an HDMI cable, in this case a USB-C to HDMI cable.
Mobile phones
Many recent mobile phones can produce output of HDMI video via either a micro-HDMI connector or MHL output.Some older phones may use SlimPort to achieve similar result.
The HDMI Alternate Mode for USB-C allows HDMI-enabled sources with a USB-C connector to directly connect to standard HDMI display devices, without requiring an adapter. The standard was released in September 2016, and supports all HDMI 1.4b features such as video resolutions up to Ultra HD 30 Hz, and Consumer Electronic Control (CEC).Previously, the similar DisplayPort Alternate Mode could be used to connect to HDMI displays from USB Type-C sources, but where in that case, active adapters were required to convert from DisplayPort to HDMI, HDMI Alternate Mode connects to the display natively.
