Description: The HDMI connectors are all made up of 19 pins but are available in different sizes. Type A (Standard), is the most widely used type of HDMI connector, commonly found on TVs, projectors, set-top boxes, and laptops. The Type C (Mini) HDMI connector is used majorly on tablets and laptops having a slim profile or ultrabooks. The Type D (Micro) is also used on slimmer tablets and high-end smartphone devices. While HDMI is primarily a consumer-focused product, there exists a Type E HDMI connector as well, that is used for automotive purposes.
HDMI is developed primarily for consumer-electronics applications: Blu-ray players, TVs, video projectors, and similar purposes. It has been widely implemented on all media devices around you, and you're most likely to be using one already.
