What is HDMI?

HDMI stands for High-Definition Multimedia Interface, and it is a standard for transmitting digital video and audio from a source, such as a computer or TV cable box, to a computer monitor, TV, or projector at the same time. It was created by a consortium of electronics manufacturers and has since become widely used, with almost all televisions and computer monitors supporting the interface.

The HDMI initiative began in 2002 to improve existing connectivity standards (e.g., DVI, component video) by developing a smaller connector, adding support for embedded audio, and delivering a higher resolution video signal. HDMI's success was such that by 2008, shipments of HDMI-enabled devices had surpassed those of DVI.

HDMI Cables

The HDMI interface enables a port to send high-resolution digital video, theater-quality sound, and device commands down a single HDMI cord, each designed to support a video resolution and features in the HDMI specification.

There are also various HDMI cable types. The logo is not used on all cables, but the cable specifications should state whether it is Standard, High Speed, Premium High Speed, or Ultra High Speed. If no type is specified, assume Standard.

HDMI Ports and Connectors

Type A (Standard), Type C (Mini), and Type D (Micro) HDMI connectors are the most common today. HDMI Type B (Dual Link) was designed for extremely high-resolution displays but was never implemented. The HDMI Type E connector, which is intended for automotive and industrial applications, is also not shown.

The most common HDMI connector type is the Standard HDMI connector (Type A). These 19-pin connectors are found on nearly every brand of television, computer monitor, game console, streaming device, and desktop computer.

Types of HDMI cables

– Standard HDMI

Mini HDMI connectors (Type C) have 19 pins and offer the same features as full-sized Type A connectors but in a smaller, more compact form factor. It is typically used on portable devices such as DSLR cameras and tablets due to its smaller size.

 – Mini HDMI

Micro HDMI (Type D) connectors are about half the width of Mini HDMI connectors but retain all of the functionality of their larger siblings. Micro HDMI connectors are found on small, portable devices like phones.

– Micro HDMI

 Your standard HDMI cable is converted to a Micro HDMI connection by the HDMI to Micro HDMI Adapter. Connecting your digital camera, video camera, media player, or game console is just one of the many possibilities. This micro HDMI adapter works with a wide range of mobile devices.
