In terms of cables, there is no distinction between HDMI versions before. For example, the cables of HDMI 1.1 and HDMI 1.3 versions are the same, but in the HDMI 1.4 version, there are some changes in the cable. HDMI 1.4 version includes 5 types of cables, each with its own different functions and performance characteristics.
HDMI 1.4 version is divided into five types: standard HDMI cable, standard HDMI cable with Ethernet function, car HDMI cable, high-speed HDMI cable, and high-speed HDMI cable with Ethernet function. The standard HDMI cable supports 1080p, and the high-speed HDMI supports advanced display technologies including 4k×2k, 3D video, Deep Color, etc.
This kind of cable is actually the previous HDMI 1.3 version, and their bandwidth requirements are all within the HDMI 1.3 version. Within the bandwidth provided. The high-speed HDMI with Ethernet function also has a dedicated data channel, that is, the HDMI Ethernet channel that provides network functions between devices.
The structure of the cable has changed, which will be introduced later. In the HDMI standard, certification labels for these five types of cables are also specified in detail. In this evaluation sample, we also selected some cables labeled as HDMI 1.4 version, but they have not been strictly implemented in accordance with the HDMI standard.
