Contrary to what many think, TV HDMI connections are not the same. There are different types, they have differences and we will explain them here below.
As he recalls a report published on the website of computer todaythe HDMI standard, which stands for High Definition Multimedia Interface, unified the audio and video signal in a single cable, leaving in the past the RCA system that accompanied, for example, game consoles or users of DVD devices.
There are different versions of HDMI, some prepared to support higher resolutions. An unknown to many is the HDMI ARCwhich has advantages over conventional HDMI.
What is HDMI ARC?
HDMI ARC stands for High Definition Multimedia Interface Audio Return Channel and he answers with his name the big difference: it saves us time and space because it is about a dedicated connection for sound.
It allows you to send the audio from the television to a sound bar or to another audio system without the need to use the fiber optic cable of these equipment in parallel.
In this way, we would only need two HDMI cables to improve the audio of the TV, one for the sound bar and the other for the TV.
Other versions of HDMI are 2.0 and 2.1, new variants to support higher resolutions. Each one includes new functions that translate into greater bandwidth, so it allows to increase the resolution of the image or the frequency of the same.
When buying your new television, you should not only see if it includes HDMI inputs, but also check the version of these and verify if one of them is ARC, especially if you want to get good sound.
