Designed to overcome the limitations of the person plug, which was a fully analog connection, the HDMI multimedia interface or the HDMI cable has become a must for multimedia installations. Existing in several types, HDMI cable plays many roles within the latter. However, to fully enjoy the benefits of using this multimedia accessory, it is necessary to obtain the best on the market. Find out everything you need to know about the high-definition multimedia interface in this article.
HDMI Cable: What is it?
The HDMI (High Definition Multimedia Interface) cable refers to a connector consisting of electrical cables wrapped in a sheath, with a metal connector at the end with 19 or more pins. HDMI cables are designed for both professional and domestic use.
What is the use of an HDMI cable?
The HDMI cable performs an essential function in a multimedia installation. This accessory is used to transfer a stream of multichannel audio (sound) signals in high definition. In other words, the HDMI cable connects two multimedia devices. For example, this accessory can be used to connect:
- A game console (Xbox, PlayStation, Wii…) on a TV;
- A Blu-ray or DVD player on a TV;
- A computer to a TV, which allows you to have on a large screen, all the multimedia content of your computer.
In addition, As you can already imagine, HDMI cable is not a cable like any other. With 19 pins, it combines the equivalent of 8 audio cables and 5 video cables in one. This particularity allows it to meet all the needs of a home cinema installation. The HDMI cable can carry the digital signal in high definition for both image and sound. For the latter, the HDMI cable also supports multichannel partition in different formats, including formats:
- Dolby Digital;
- DTS HD;
- Dolby True HD and more.
Different types of HDMI cables
As explained above, there are different types of HDMI cables. Each of these has specificities that make it possible to distinguish it from the others.
Type A or standard HDMI cable
Undoubtedly the most well-known type, the standard HDMI cable, has been designed for universal uses. It can transmit in high definition, including from 720p to 1080p. The standard HDMI cable is ideal for satellite TV, screen projectors, DVD players, Blu-ray players, game consoles, and other common screen types in terms of usage.
Le type B (Dual-Link)
The HDMI Type B cable is designed with more pins, including 29, transmitting data in very high definition. This HDMI cable can support resolutions above 1080p. By choosing this cable, we can hope to achieve resolutions ranging from 4k to 60 Hz. The high-performance HDMI Type B (Dual-Link) also includes display technologies such as 3D and Deep Color. In a configuration where a 1080p screen must be connected to a 1080p source such as a 4k game console or Blu-ray drive, the B-type HDMI cable is the right choice. Furthermore, it should be remembered that HDMI B cable is not as widespread as type A cable. This is so because Type B is only used for transmissions in very high resolution.
Le type C (Mini HDMI)
The TYPE C HDMI cable is very similar to Type A, as it shares several commonalities with the latter. These include the number of pins and other features. The fundamental difference between the two types of HDMI cables is in their size. Indeed, as its name already indicates, the HDMI Type C cable (Mini HDMI) is a smaller model than the type A. It connects touch tablets, digital cameras, or camcorders to a monitor.
Type D HDMI cable (Micro HDMI)
The HDMI D (Micro HDMI) cable is similar in some respects to the HDMI type A cable, particularly in terms of the number of pins, and stands out in other ways. For example, it is more compact than the HDMI A cable and connects smaller devices. The Micro HDMI cable can connect certain models of tablets or smartphones of the latest generation.
Type E HDMI cables
Although present in this categorization, type E HDMI cables are not accessible to the general public. It is a type of cable that is only used in the automotive industry. These users are, therefore, the automakers who use it for various purposes.
Thanks to their various uses, HDMI cables have become a must in everyday life. Because of the presence on the market of several manufacturers, the quality of this multimedia tool varies from manufacturer to manufacturer. Taking into account several decisive criteria makes it possible to make the best possible choice.
How To Choose HDMI Cables
The various criteria that are here prove crucial to choosing a high-quality HDMI cable.
HDMI cable standard
All HDMI cables are manufactured to standards. These are clearly marked on the packaging of each HDMI cable. Considering the standard before making a purchase is important, as the specificities and characteristics of each cable vary according to this criterion. Today we find the 1.3 standards; 1.4 and 2.0.
HDMI 1.3 Cable
Launched in 2007, HDMI 1.3 has fewer features than the last two. It is not compatible with the 3D stream that the latest generations of TV have. This standard also does not ensure the transport of Ethernet data. If you want to use these features, the idea is to focus your choice on another standard.
HDMI 1.4 Cable
Higher than the 1.3 standards, HDMI 1.4 offers better functionality. It was launched in 2009 and is proving to be retro compatible. This means that if you own a non-new TV model, you can still use it. Compared to the previous one, there are two major new features on this standard. This is 3D support and Ethernet support.
HDMI 2.0 Cable
Released in September 2013, HDMI 2.0 is the latest standard on the market. It is retro compatible with 1.4 and 1.3 standards to be used with older TV models. This HDMI cable is the most powerful part of the moment. The HDMI 2.0 cable is compatible with all 4k content (up to 60hz) and can support up to 32 audio channels, a true performance compared to previous standards. The maximum throughput that can be reached has also increased: it is now 18Gb7/s with the standard 2.0. Although a 2.1 standard has already been designed, it is not yet available to the general public. In addition, the versions of multimedia devices with which they will be used are not yet designed.
Of the three HDMI cable standards you’ve just discovered, your choice will be based on your needs. Getting an HDMI 1.4 cable when you need the capabilities of an HDMI 2.0 cable would be a bad choice. If you feel any doubts, you can ask your supplier for advice at the time of purchase. Competent and experienced, the latter will guide you towards a wise choice. It should also be noted that the amount to be paid for the purchase of an HDMI cable will vary depending on the standard on which you are based.
The length of the HDMI cable
The length of the HDMI cable is also an important factor to consider before making the purchase. In fact, the two media devices you want to connect may be close or distant from each other.
If the two devices to be connected are separated by a distance of less than 7.5 m, you will not need a specific HDMI cable. The one you acquire will do the job perfectly: there will be no signal loss, and all functions (4k, ARC, 3D) will be transmitted without any difficulty.
If the two aircraft are more than 7.5 m apart, a signal loss may occur. The traditionally recommended solution, in this case, is the use of the signal amplifier, also known as the repeater.
A model with or without a swivel connector
If the media device (television, Blu-ray player, game console…) that you want to connect is against the wall, plugging in the HDMI cable can be difficult. The solution, in this case, is to wear your choice on an HDMI cable equipped with a swivel connector.
Now that you know the different criteria to consider when buying your HDMI cable goes to a good supplier to get the best.
