Technical Specifications of the HDMI 2.0 Cable of 15 Meters Male/Male
The audio also includes improvements, as it offers an audio return channel that will require fewer cables to have a surround sound system connected to the TV.
How do I know that an HDMI cable is of quality?
To evaluate the quality of an HDMI cable, components and the type of manufacture must be taken into account.
To determine the quality of the cable, we must consider the following points:
Driver:
The conductor must be multiwire. They must not be conductors with a single central wire.
The conductor must be made of copper, and not copper-plated steel or other lower-cost alloys.
The number of conductors must be 19 since these are the stipulated pins conceived in the standard and not 15 wires, which limits the use of future applications.
The conductors must be twisted and equipped with shielding mesh. Like any type of data cable. Without shielding it would not comply with the CE directive.
The cover:
The cover must comply with the RoHs directive, so that it does not contain contaminating elements.
The cover should not have excessive wrinkles and folds.
