HDMI-HDMI cable 1,5m blister pack Televes

HDMI cables, which connect the device generating the signal (Blu-ray players, computers, DVB-T or HDTV receivers, etc.) to the television, 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 function 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 acronym ""HDMI"" should oblige compliance with the requirements of the entire list of specification data, so it would be a mistake to identify it with just one connection method. The lack of information and the fact that such cables are used with home appliances make it easy for them to spread 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, there is still no obligation in Europe to ban products that do not meet these requirements, so the high quality of HDMI cables is guaranteed only when it is certified by laboratories such as Televés.

What distinguishes an HDMI cable?

The type of material and the manufacturing method play an important role in cable production, especially for internal conductors and the outer sheath. Below we present several 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 providing flexibility, which allows the cable to retain its functions 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.

Furthermore, there are cases where, instead of conductors made of copper, copper-clad steel or other low-quality alloys are used, which fail positive attenuation and ""Jitter"" tests, 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 cable's use for other applications in the future.

Conductors should be twisted and have a shielded braid. As with any type of cable, these two elements prevent 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. A breach of the rules means the cable is a pollutant and is also harmful to the environment.

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