The evolution of technology has brought
with it the emergence of various devices and gadgets meant to help us. Televisions have begun to play an
essential role in people's homes. Through them, most people managed to create a home cinema system right at
home. Of
course, various devices have appeared.
These were created to be able to make the connection between the TV and the
internet or connect the laptops directly to the TV screen. To get more TV functions
it is important to know what equipment is needed.
1. What is HDMI and how to choose it
Everyone who has a high-definition TV or
a home cinema system is familiar with this term, HDMI cable. HDMI is the abbreviation for
High-Definition Multimedia Interface, and its name basically shows what you can
do with such a cable.
Mainly, you need to know that everything that means high-definition
content, audio and image, is transmitted through a single cable. Another thing
you need to know about HDMI cables is that there are several versions. These are: HDMI 1.0, HDMI1.1, HDMI 1.2, HDMI 1.2a, HDMI 1.3, HDMI 1.4, HDMI 2.0 & HDMI 2.1
There are not many differences between
these variants and they use the same types of connectors and retainers: each
new variant is compatible with previous models, so you will not have any
unpleasant surprises!
Any audio or video equipment you have can be used with
any HDMI model, regardless of the latest version. It is important to mention
that HDMI 2.0 supports 18 Gbps, HDMI 1.3 10.2 Gbps, HDMI 1.0 4,95 Gbps.
Since 2013, two versions of HDMI cables
have appeared. Specifically, it is HDMI 2.0 and HDMI 2.1. The HDMI 2.0 cable supports 4k
up to 60 fps. This allows for full-resolution 4k 3d along with higher
frame-rate 2d content. An important thing about HDMI 2.0 is that it supports
dual video streams so you can get two full HD shows on the same screen at the
same time.
HDMI Ethernet Channel (HEC)
HDMI Ethernet Channel is the most interesting feature
added with version 1.4. By using this
function, up to 100 Mbit / s can be transmitted via the same cable internet
traffic. With this HDMI you can share a single Internet connection between two
devices.
HDMI ARC (Audio Return Channel)
With the advent of the HDMI Ethernet Channel, the HDMI
Audio Return Channel option has been added. HDMI ARC is an
abbreviation for return audio channel.
HDMI CEC (Consumer Electronics Control)
The CEC function allows the control of several devices
using a single remote control. The maximum
number of devices that can be controlled by a single remote control is 15.
3. What is an HDMI cable high speed
There are several types of HDMI cables depending on your preference. It is very important to know exactly what you want from this HDMI. If you know what you want to use it for, it will be much easier for you to buy the most suitable option for you.
The standard speed of an HDMI cable is 1080i. There is a possibility that they can support a higher speed but they are generally created for a speed of 1080i.
High-speed HDMI cables are created to withstand a speed higher than 1080i.
It is important to know that HDMI cables exist in 5 types of connectors. The A / B type are representative of the HDMI 1.0 specifications. Type C is designed for HDMI 1.3 specifications. HDMI 1.4 falls into the category of type D ones.
4. How to recognize an HDMI cable high speed
Each HDMI cable is designed to support a certain amount of data. Thus, the price of each type of HDMI cable differs. If you choose to buy a cheap cable but still have high demands on it, you may be disappointed. You will need to evaluate what you want from an HDMI cable and choose the right one based on your requires. HDMI 1. 0 no longer meet current consumer requirements.
If you want an HDMI cable that offers high speed, to be able to play a 4k resolution you must choose HDMI 2.0.
HDMI 2.0 cables are also known as High-Speed HDMI cables. These were created to handle the 18 Gbps.
It is also important to note that HDMI High Speed cables are more expensive. If you want premium quality and a higher speed you have to buy this type of cable. HDMI 2.1 cables offer a higher speed than its previous version.
They are also found under the name of Ultra-High-Speed HDMI and it handles a huge amount of data.
If you have recently purchased an HDMI cable of type 2.0 or 2.1, it means that it is able to support a very high speed and offer you high quality.
But if you have an earlier version of category 1, this cable may not meet your requirements. If you want to make an update, the only option is to go to a store and buy a new cable. You can choose between version 2.0, High-Speed HDMI cables or version 2.1, Ultra High- Speed HDMI.
Conclusion

With the evolution of TVs and the addition of additional functions, several versions of HDMI cables have appeared.
