The most important thing we need to know about HDMI

What is HDMI?

Technically HDMI stands for High-Definition Multimedia Interface (multimedia interface with high resolution). The cable is a global standard for communication, developed by a consortium of some of the largest electronics manufacturers, including: Sony, Hitachi, Philips, Panasonic, Thomson (RCA), Toshiba and Silicon Image. Today more than 800 companies use the HDMI standard in their products.

This means that one cable can connect all components of a system of “home theater” (TV, DVD player, game consoles, monitors, etc.) With high quality picture and sound without reservations, who the manufacturer is and if the product will be compatible.

HDMI cables are the best and easiest way to play audio and video, you can buy. High-Definition Multimedia Interface or HDMI is the only way that you can experience 1080p resolution. This definitely means that if you want to fully enjoy the new generation of movies with amazing quality of sound and picture, you should use high quality HDMI cable.

Unlike some other cables, HDMI transfers not compressed and fully digital image data transmitted between devices. HDMI eliminates the need for complex connections between sound and picture. It replaces several cables at once. And of course the end result is perfect picture and sound with just one easy connection.

All in one!

HDMI provides the same, all-digital signal, transfer of sound (up to eight channels at the same time), which would consist of at least 3 individual video cables and at least one audio, in order to achieve the same effect in the quality of picture and sound. With HDMI, all this information is transmitted flawlessly with a reliable cable. For all features that today’s “home theater” offers (satellite and cable operators, Blu-ray, game consoles and countless different ways of entertainment) HDMI is much easier, “clean” and less confusing way to connect.


What to look for?

Each HDMI connector integrates 19 cable pairs, which must have exactly the same length and the corresponding factors to convey precisely the bits that make up the digital audio and video signal. These bits must be transmitted perfectly harmonized to allow the data to be interpreted correctly. Therefore, all HDMI cables on the market are designed, manufactured and tested with very little lenience before being marked with the official HDMI logo.


However, not all HDMI cables are identical. Especially when using cables more than 10 meters long, the quality can suffer!

Distinguishing factors can be:

Materials: characteristics – such as the thickness of the wire and insulation, shielding and shield design that increase the reliability of the cable.

Speed ​​Rating: higher speed rating represents higher bandwidth.

Bit depth rating: 8 bit from basic to high-end cables – 12 or even 14 bits.

Maintenance of specific functions: This is one of the most important factors that encourage you to take into consideration. These “specific” features may include: resolution 1080p (or higher), a higher rating to “frame” 120Hz or 240Hz, deep colors, automatic synchronization, etc.
