HDMI connector is a cable that transmits audio and video signals from one device to another through a high-speed digital signal transmission interface. HDMI connectors can connect various devices such as televisions, computers, cameras, game consoles, etc., making information transmission between them more efficient and stable. HDMI connectors have many advantages, among which the highlight is high definition. The HDMI connector can transmit 1080p high-definition video signals, which means you can have a clear and realistic visual experience without worrying about blurry or pixelated images. The HDMI connector also supports 3D video transmission, allowing you to experience cinema like 3D effects at home. In addition to high definition, HDMI connectors also have high-quality audio transmission capabilities. It can transmit multi-channel audio, including Dolby Digital, DTS, and other audio formats. This means you can enjoy cinematic sound effects at home, making your viewing experience more realistic.

HDMI connectors also have the advantage of being easy to connect and operate. It only requires one cable to connect multiple devices and does not require an additional power adapter. The HDMI connector also supports bidirectional communication, allowing for more intelligent interaction and control between devices.

Overall, HDMI connectors are a very practical digital transmission interface that can provide high-definition, high-quality audio, and easy-to-use connection methods. If you want a visual and auditory experience, be sure to consider using HDMI connectors.

HDMI connector types

In our daily life, HDMI interface connectors can be divided into 5 types, namely A type, B type, C type, D type, and E type. These different types of interface connectors have different functions and meet different user groups.

The C-type HDMI interface connector is a mini HDMI connector, smaller than the A-type connector, with a size of 10.42mm x 2.42mm and a 19 pin configuration.

4. HDMI D-type interface connector

The size of the HDMI Type D interface connector is very similar to that of the micro USB connector, so the D type is commonly referred to as micro HDMI. The measured value is only 6.4mm x 2.8mm. Within this contour, micro-HDMI retains 19 pins from other connectors, but the pin assignments are different.
