HDMI arc what is it on TV
Modern TVs, both middle class and higher, and sometimes even budget models, are gradually acquiring various fashionable things. The buyer is sometimes surprised to discover several different connectors for different interfaces at once. And almost always there is an HDMI arc connector, sometimes even more than one. So users are wondering what is connected to this connector and, most importantly, how.

HDMI what is it on TV?
Modern TV models, both plasma and LCD, are equipped with a large number of connectors. You can connect several different devices to them at the same time. This interface saves space, since the same cable transmits both video and audio in two directions. As a result, only one cable is required instead of several.
The cable provides high signal quality. The image comes with a resolution of about 1080 pixels, and the sound provides eight channels with a frequency of 182 kilohertz. This is enough to meet the high requirements of the media content standard.
This protocol was developed in 2002 and is widely used in household appliances.
IMPORTANT! When buying a TV, be sure to check whether it has an HDMI jack. What is it for? With its help, an audio-video signal of increased quality is transmitted. All data on this interface is copy protected.
HDMI has the following characteristics:
- It has high throughput (about 18 Gbit/s);
- The cable is very long (standard length is about 10 meters, up to 35 meters are available);
- Supports CEC and AV.link standards;
- It is compatible with DVI interface. There are various adapters that allow you to work with equipment that does not have HDMI.
The cable can easily be equipped with protection against various interferences. Anyone who understands electronics and knows how to hold a soldering iron in their hands will be able to put rings on the cable, at the very beginning and at the end. These rings will cut off interference.
It is possible to increase the range of the transmitted signal; for this you will need to use special video senders and amplifiers. The HDMI interface is an alternative to similar connection types - SCART (Euro-AV) and RCA (regular AV).
What does it look like?
Externally, the connector is similar to USB with beveled corners.
The metal part of the nest can be painted metallic or gold. This is not reflected in performance, it is purely a whim of the manufacturers.
The cable is easy to use. No special knowledge in the field of high technology is required for this. The only thing you need:
- The required connector on a TV or monitor is for it to receive image and sound;
- Transmitting device;
- And the cable itself.
One end of the cable is inserted into the translator socket, and the other into the receiving device. Enter the required settings and get to work. Nothing complicated.
There are several options, each with 19 contacts:
- Regular HDMI (Type A);
- Type Mini (Type B);
- Type Micro (Type C).
The cable is designed somewhat unusually compared to others. From the outside, it is protected from mechanical stress by a special shell.Next is the braid for shielding, it is made of copper, which is usually used for soldering, there is an aluminum shield and a polypropylene sheath. Inside there are communication cables (they look like “twisted pair”), as well as separate wiring for power supply and other signals.
With this cable you can turn your TV into a multimedia station. A cable with an HDMI interface allows you to control all devices connected to the TV with one remote control, and in the near future it will be possible to control it from a computer.
REFERENCE! If you have a desire to turn your TV into a multimedia station with many functions, then for this you will need to buy a special “smart” smart set-top box or a board with the same characteristics.
With their help, you can watch paid channels in digital quality mode.
Where is this connector located?
This connector is usually located on the back of the TV, however, on some models it may be located on the side.
Do not under any circumstances be fooled by the seller’s assurances that cables with golden-colored connectors are much superior in their characteristics to similar cables with metallic-colored connectors. Remember, this is just the color of the metal. The entire base, which is responsible for the quality of the cable, is located inside it.
NOTE! Be prepared for the fact that when you connect a device with an HDMI connector to your TV, they will not always see each other immediately. As a rule, the necessary settings should be made.
Most often, the HDMI interface is used to connect a TV to a computer. Modern televisions have a much larger diagonal size than computers, which allows them to be used to create a “home theater.”When making this connection, do not forget to first turn off both devices, as otherwise there is a possibility of burning the ports.
Despite the existence of various adapters, try not to use them, as this significantly reduces the signal quality.
