The HDMI interface was proposed in 2002 and has now evolved to the HDMI 2.1 standard. The HDMI 2.1 standard can support 4K 120Hz and 8K 60Hz, supports high dynamic range imaging (HDR), can be optimized for scenes or frame numbers, and is backward compatible with HDMI 2.0 and HDMI 1.4. The most important thing is that it transmits both video and audio simultaneously.

Nowadays, many monitors have built-in speakers, and using a single HDMI cable can simultaneously transmit images and sound, which is also a major advantage of HDMI. Because of this, HDMI has become the most common interface for displays today. There are several types of HDMI on physical interfaces. There are mainly standard HDMI interfaces, mini HDMI interfaces, and Micro HDMI interfaces. For long-distance transmission of HDMI cables, the wire is generally hard, so it is recommended to use devices with standard HDMI interfaces as much as possible to obtain a stable connection. The Mini HDMI interface and Micro HDMI interface are more suitable for small devices.

In 2018, the HDMI Association launched the HDMI 2.1 standard. Currently, the bandwidth of HDMI 2.0b is 18Gbps, while HDMI 2.1 has been increased to 48Gbps. It can fully support lossless videos with resolutions such as 4K/120Hz, 8K/60Hz, and 10K, and also supports high dynamic video HDR technology. Therefore, the new standard adopts a new Ultra High Speed HDMI Cable.

Dongguan Xianhe Electronic Technology Co., Ltd. in Guangdong Province has been developing HDMI products since 2008, with rich development experience and proficient quality control capabilities. The main types of development include sinking plate SMT mother seat, vertical SMT mother seat, horizontal SMT mother seat, clamp type male head, welded wire type male head, etc.
