What is HDMI alt mode

HDMI, or High Definition Multimedia Interface, is a digital interface that allows for the transmission of high-definition video and audio signals. HDMI alt mode is an alternate mode of the USB Type-C connector that allows HDMI signals to be transmitted over a USB Type-C cable. This allows for the use of HDMI cables with devices that have a USB Type-C port, such as laptops and smartphones.

HDMI alt mode is also known as HDMI Adapter Mode. In order to use HDMI alt mode, the device must support the protocol and the correct cable must be used. The cable must be able to carry both the video and audio signals. When using an HDMI alt mode cable, the video and audio signals are transmitted over the USB Type-C connector at a higher bandwidth than is possible with other types of connections. This allows for the transmission of high-definition video and audio without any degradation in quality.
