How to pick a qualified HDMI cable?

December 13, 2024
The same HDMI protocol cable, will be used because of the core material, showing different performance transmission differences.
 
Ordinary HDMI CABLE using a copper cable core, copper cable core can also be synchronized audio and video transmission, and affordable, cost-effective. But in long-distance transmission, easy to produce loss, resulting in signal attenuation, which is part of the user exclusion of ordinary HDMI cable.
Some better HDMI cables use oxygen-free copper, silver-plated oxygen-free copper, tin-plated oxygen-free copper cores. Has a better than ordinary copper wire oxidation resistance, conductivity, can effectively shield interference, is conducive to improving signal transmission performance. HDMI cable with this type of material as the core, occupies the mainstream market.
 
Of course, in terms of good transmission performance, of course, fiber optic HDMI cable wins. This type of cable basically adopts the structure of optical fiber + copper wire, containing a fiber optic core. This means that the data is transmitted in the form of light through the fiber, without the flow of current, to avoid the impact of electromagnetic interference, which can solve the copper wire because of the signal loss caused by long-distance transmission. However, the price of fiber optic HDMI cable is not cheap, usually several times the conventional HDMI cable.
 
2, shielding and connector differences
 
The role of the shield and connector is to prevent electromagnetic interference and radio frequency interference, to ensure the stability and reliability of signal transmission.
Ordinary level HDMI cables, in addition to the PVC outer cover, the general core will also have 2-3 shielding layers, such as aluminum foil shielding, metal braided mesh, plus (pure copper, tinned copper) ground. High-quality HDMI cables, may be appropriate to increase the number of shielding layers, as well as the addition of tensile materials to improve the durability of the wire, to reduce the loss of bending, stretching and extrusion of the wire.
The connectors can also tell the strengths and weaknesses of the HDMI cable. Ordinary connectors use metal connectors and plastic shells, poor durability, may also cause signal loss over time. High-quality HDMI cable, the connector will increase the gold-plated process to improve oxidation resistance and electromagnetic shielding ability; shell is mostly aluminum alloy, zinc alloy and other alloy shell, more durable, outstanding quality.
 
Summarized in one sentence, “all good cable, not cheap”! So users often fall into another question “is it worth it, should I buy?
