The production process of HDMI cable determines its quality?

A. The production process of HDMI cable determines its quality? Generally speaking, a good HDMI cable, should use pure copper as the inner core, so as to ensure the quality of the transmitted signal. Those who cut corners and have low quality HDMI will use iron cores or other alloy materials that cost much less. Because we can't see what material is used inside when we buy HDMI cables, we can only judge by feel. Generally speaking, HDMI with a copper core is softer and easier to bend, but HDMI with an iron core is not, because iron cores are hard to bend. If you are in a position to do so, you can also conduct a magnet test, which can determine whether the HDMI cable uses an iron core. A good HDMI cable is not too soft and not too hard, and the flush line is simple to use, no impedance, no signal loss, high stability, no electromagnetic interference combination.
