HDMI Cable Detailed Explanation: Evolution of Connector Types and Versions

  As an indispensable electronic device connection tool in modern families, HDMI cables are widely used to connect smart devices to TVs or computer monitors, and young people use them to connect game consoles (such as the Steam platform) to home theaters. HDMI, or High Definition Multimedia Interface, has gradually replaced the DVI interface that can only transmit video signals since its launch in the early 2000s, and has achieved synchronous transmission of video and audio digital signals.

  HDMI Cable Connector Types
  HDMI cables have undergone many updates and derived a variety of connector types, but the three most common and most needed ones are:
  Type A connector (standard connector): This is the most widely used and readily available HDMI connector. It is larger in size and compatible with large devices such as desktop computers, TVs, and game consoles.
  Type C connector (mini connector): The main difference from the standard connector is the size. It is suitable for small devices such as camcorders, small cameras, etc. There are many types of mini C connectors, such as mini to mini, mini to standard, etc.
  D-type connector (micro connector): Designed to solve the problem of transmitting audiovisual signals from extremely small devices (such as mobile phones) to large screens (such as laptops and TVs). It looks like a USB connector, but its functions are different.
  HDMI version evolution

  Since its first release in 2002, the HDMI cable has undergone several version updates, each of which has improved on the previous version:
  HDMI 1.0 (2002): Uses the DVI format, but relies on audio transmission. Can transmit Blu-ray disc audio and video data at a speed of 4.95Gbps and full resolution.
  HDMI 1.1 (2004): The main upgrade lies in electrical changes, allowing direct display of video and audio at the same time.
  HDMI 1.2 (2005): Introduced major changes such as direct stream digital, YCbCr color compatibility, and availability of type A connector.
  HDMI 1.3 (2006): Color resolution increased from 10 bits to a maximum of 16 bits, and data transmission speed and single link bandwidth increased to 10.2 Gbps and 340 Mhz respectively. Introduced the mini C-type connector.
  HDMI 1.4 (2009): Added features such as Ethernet connection, 3D video compatibility with 4k x 2k HD resolution, and introduced the micro D-type HDMI connector.
  HDMI 2.0 (2013): The bandwidth increased to 18 Gbps, supporting high UHD video resolution of 4k @50 Hz or 60Hz. The number of transmittable audio channels increased to 32, supporting dual video streams and multi-audio transmission.
  HDMI 2.1 (2017): With 10k @ 120Hz video resolution function, the data transmission line reaches 48G. For example, the 48 Gbps ultra-high-definition HDMI cable produced by CableCreation can achieve video resolutions of 8K@60Hz, 4K@120Hz/60Hz/30Hz.
  By understanding the evolution of HDMI connector types and versions, we can better choose the HDMI cable that suits our needs and enjoy a higher quality audio-visual experience.
