HDMI-HDMI cable 3m blister pack Televes [494502]

HDMI cables, which connect the signal-generating device (BluRay players, computers, DVB-T or HDTV receivers, etc.) to a TV set, are not ordinary cables carrying analogue signals like SCART cables. In fact, they are data transmission cables that carry digital signals via the various conductors that make them up.

For an HDMI cable to work correctly, it must meet standards classified according to a certain ""Category"". Quality standards for this type of cable are little known to both professionals and end users.

Using the name ""HDMI"" should mean meeting the requirements of the full list of specification data, so it would be a mistake to associate it with just one method of connection. The lack of information, and the fact that such cables are used in household equipment, makes it easy to spread them on the market without meeting the quality required by regulations.

A user buying an HDMI cable should know that:

Despite the existence of the HDMI specification, in Europe there is still no obligation to ban products that fail to meet these requirements, so high quality HDMI cables is only guaranteed when it is certified by laboratories, such as those held by Televés.

What distinguishes an HDMI cable?

The type of material and manufacturing method play an important role in producing the cable, especially for the internal conductors and outer sheath. Below we present some aspects that will help us assess product quality:

Internal conductor:

The HDMI standard specifies that the conductor should be multi-core. This type of conductor ensures compliance of electrical measurements while also providing flexibility, allowing functionality to be maintained even when installed in tight spaces. There are many cables on the market fitted with single-core conductors, which brings significant cost savings but also a significant reduction in achievable functions.

Moreover, there are cases where, instead of copper conductors, copper-clad steel or other low-quality alloys are used, which fail positive attenuation tests, ""Jitter"", etc.

According to the standard, the number of pins should be 19. Some manufacturers, disregarding the standard, produce cables with 15 pins, which will limit the future use of the cable for other applications.

Conductors should be twisted and have a shielded braid. As with any type of cable, these two elements help us avoid problems such as crosstalk or signal coupling between pairs. Without shielding, an installation using an HDMI cable will not comply with the CE directive, so selling unshielded cables in Europe would be unjustified.

Outer sheath:

One of the most important aspects of assessing outer sheath quality is compliance with the RoHS directive. Breaching the rules means the cable is a contaminant and is harmful to the environment.

Excessive creasing and folding increases the risk of the protective sheath cracking, causing the cable to lose its properties.
