HDMI 2.0 is here. What is new?

The new HDMI 2.0 standard has finally arrived, but since the connector is exactly the same in appearance to previous models, many people are not aware of which are its upgrades. Therefore, in this article we’ll take a little look back to the first version, and we’ll tell you exactly what this HDMI 2.0 gives us over previous versions, from HDMI 1.0 to HDMI 1.4, reviewing versions 1.2 and 1.3.

We begin by explaining that HDMI is a standard that allows us to transmit high definition video and multichannel digital audio through the same cable. For practical purposes, the arrival of the first HDMI standard meant to replace the old Euro-style type of connection that is still used today, even though the first HDMI was released on the market back in 2002, twelve years ago. It was the HDMI 1.0, a new type of connection that marked the transition from analog to digital, and its entry into our homes was very satisfying, because at that time the first DVD players were the hottest new thing, and we began to see the first TDT through external tuners.

HDMI 2.0

This first HDMI 1.0 offered a transfer rate up to 4.9 Gbps and had support for 1080p resolution at 60 Hz, with eight audio channels and 192 Khz. Again, to support DVDs players.

The first HDMI standard revision passed directly to version 1.2, three years later. The main novelty was that it supported compatibility with PC monitors, with a good range of different resolutions. This standard was quickly implemented in the world of PCs for this reason. In addition, it provided support for One Bit Audio for the first time.

Then, HDMI 1.3 version emerged less than a year later, and it already provided a bandwidth of 10.2 Gbps, providing support for colors of 10, 12 and 16-bits and the formats Dolby TrueHD and DTS-HD audio, already used in Blu-ray (keep in mind that we were already in 2006). A new type of HDMI connector also appeared around that time, aimed at cameras.

And in 2009 the HDMI 1.4 appeared, which is the one that we have been using until now. This standard supports resolutions of 4096 x 2160 pixels (4K), yet as much at 30 FPS, 3D video, and we saw the release of the new Micro HDMI connector, oriented to mobile devices.

HDMI 2.0

It has taken many years to make the leap to HDMI 2.0, but it is finally here. Audio quality is improved to 32 channels and 1536 KHz with up to four simultaneous sound sources. It also comes with support for 4K resolution at 60 Hz, but note that you need a cable designed for this. On the other hand, the transfer rate has also gone up, up to 18 Gbps, which already makes it possible to reproduce 3D video at high resolutions with different audio sources.
