Modern TVs as plasma and LCD are equipped with a large number of connectors. At the same time it is possible to connect several different devices. This interface allows you to save space, since one and the same cable, and transmits video and audio signals in both directions. As a result, it takes only a single cable instead of several.
The cable provides a high quality signal. The image comes from the resolution of the order of 1080 pixels and provides eight channels of sound with a frequency of 182 kilohertz. This is enough to meet the high requirements of the standard media content.
This protocol was developed in 2002 and is widely distributed in household appliances.
IMPORTANT! Buying a TV, be sure to check whether there is in him an HDMI jack. And what is it? With the help of transmitted audio and video high-quality signal. All data of this interface are copy protected.
For HDMI characterized by the following:
- It has a high transmittance (approximately 18 Gbit / s);
- Cable is very long (for the standard length of about 10 meters, and there are up to 35 meters);
- It supports standards CEC and AV.link;
- It is compatible with DVI interface. There are various adapters that can handle the technique has no HDMI.
The cable can easily be equipped with protection against various disturbances. Anyone who understands and knows how to keep the electronics soldering iron in hand can put on the cable ring, at the very beginning and at the end. These rings are cut and interference.

There are several options, each with 19 contacts:
- Normal HDMI (Type A);
- Mini type (Type B);
- Micro type (Type C).
The cable has a bit unusual compared to the other. Outside, it is protected against mechanical damage the special coating. Next is a braid for shielding, it is made of copper, which is normally used during soldering, there is a screen made of aluminum and polypropylene sheath. Inside there are cables for connection (they appear as "twisted pair"), and a separate wiring for power supply and other signals.
With this cable, you can turn your TV into a multimedia station. The cable has a HDMI interface allows you to manage a single remote control of all devices connected to the TV, and it will be possible to manage the computer in the near future.

This connector is usually located at the back of the TV, however, in some models, it may be laterally.
In no case do not get fooled by the assurances of the seller, the cables with golden color connector is much superior to its characteristics similar to the color of the cables with metal connectors. Remember, this is just the color of the metal. The entire framework that is responsible for the quality of the cable is located inside of him.

Most often, HDMI interface is used to connect your TV to your computer. Modern TVs have a much larger diagonal than computers, so you can use them to create "home theater." Making this connection will not forget to turn off both devices, since otherwise there is the likelihood of burn ports.
Despite the existence of various adapters, try not to use them, as this significantly reduces the signal quality.
