Technical Sharing of HDMI Cable
HDMI 1.4 and later versions, regardless of cable version, are all 19+1-core structures. And HDMI cables do not have chips, they are directly connected through interfaces. Our HDMI cables over 25 meters will have multiple IC chips used to amplify electrical signals, not protocol chips. Fiber optic HDMI cables will have an additional optoelectronic conversion module.
So the commonly referred HDMI 2.0 and 2.1 versions mainly depend on the chip protocols of the output and input terminals.
For example, the computer graphics card and monitor interface are both HDMI 2.1 versions, and our HDMI 2.0 cable can also support HDMI 2.1 devices. That is to say, it supports 4K120Hz displays. But we still advertise it as 2.0, which can only reach 4K60Hz, and higher ones are not guaranteed.
