The new HDMI 1.4 specification is characterized by its high transmission speed that offers high quality video and surround audio, with the possibility of also sending data and supporting 3D images.
The 1.4 version of the HDMI also kicks off the resolution improvement we call today Ultra HD 4K. We will have to forget the before and after 1080p because this new specification is close to authentic home cinema and is capable of sending video with resolutions up to 4096 × 2160 at 24 fps or 3840 × 2160 at 30 fps.
The 20-meter HDMI cable presents version 1.4, a new improved version that offers improvements in the extended color support, so that the new HDMI can bring us to a TV more real colors especially when we connect a camcorder.
The audio also undergoes improvements, as it offers an audio return channel that will require fewer cables to have a surround sound system connected to the TV.
The 3D cinema will not take long to land in a fulminating way, and with this cable we can send data and videos of this new technology.
How do I know that an HDMI cable is quality?
To assess the quality of an HDMI cable, components and the type of manufacturing must be taken into account.
To determine the quality of the cable, we must consider the following points:
Driver:
The driver must be multifilar. They must not be conductors with a single central wire.
The conductor must be made of copper, not copper-plated steel or other alloys of lower cost.
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.
Drivers must be braided and equipped with shielding mesh. Like any type of data cable. Without shielding it would not comply with the EC directive.
The cover:
The cover must comply with the RoHs directive, so that it does not contain contaminants.
The cover must not have excessive wrinkles and folds.
