 What exactly is HDMI 2.0?

As previously said, HDMI has evolved since its inception in 2002, and current versions provide some distinct benefits. Here's an overview of the various HDMI versions and the features they added.

On December 9, 2002, HDMI 1.0 was officially published, allowing for the transmission of a digital video signal as well as up to 8 channels of audio. DVI's transmission standard was essentially used, with audio functionality added. The standard could carry data at up to 4.95 gigabits per second, which meant video with a resolution of up to 1080p and a framerate of 60 frames per second could be sent.

In May 2004, HDMI 1.1 was released, which included DVD-Audio functionality as well as a few minor changes to the electrical standard.

HDMI 1.2 was released in August 2005 as the next version of the HDMI specification. While just a few months following HDMI 1.1, HDMI 1.2 introduced a number of significant modifications to the standard, including substantially improved PC compatibility with the inclusion of low-voltage sources such as PCI Express.

In June 2006, HDMI 1.3 was announced, increasing the capacity of a single HDMI connection to a whopping 10.2Gbps. HDMI 1.3 also introduced the smaller HDMI Type C, or mini-HDMI, connection, which supports 10-bit, 12-bit, and 16-bit colour resolution per channel.

In May 2009, HDMI 1.4 was released, which brought a number of new characteristics to the connection, making it much more flexible. It adds the HDMI Ethernet Channel, for example, to share an internet connection. The addition of capability for 4K resolutions at 30Hz was maybe even better. The audio return channel, or HDMI ARC (which we'll discuss later), was also included in HDMI 1.4. This enabled a television to transfer data to a surround sound system, obviating the need for a separate audio line in higher-end systems.

The first significant version modification since HDMI's inception was HDMI 2.0, however it's impossible to say that it was even close to the original version. In September 2013, HDMI 2.0 was announced, increasing the bandwidth to 18Gbps and allowing for a 60Hz refresh rate at 4K displays. Up to 32 audio channels are now supported by HDMI 2.0. In 2015, HDMI 2.0a was announced, enabling compatibility for HDR technologies such as HDR 10.

For HDMI, the inclusion of HDR is critical. HDR, or High Dynamic Range, allows for brighter highlights, more vibrant, realistic colours, and more, resulting in a more detailed picture overall. A number of conditions must be met in order to make advantage of the HDMI functionality. To begin, you'll need a TV that supports HDR and a connection that does as well, such as HDMI 2.0. The material itself must be adjusted for HDR, which is happily becoming more common thanks to companies like Netflix. Many gaming consoles are now adopting HDR compatibility, allowing you to experience more colourful, punchier graphics while gaming. HDR is supported on the PlayStation 4, Xbox One S, and Xbox One X — but bear in mind that content must also support HDR, meaning the game itself will need to be created to take use of it.

HDMI 2.1, which was introduced in November 2017, is the most recent and best version of HDMI. This version has a 48-gigabit per second bandwidth and a large 10K resolution at 120 frames per second. This version of HDMI will take a few years to catch on, partly because, unlike previous advancements, it needs a new HDMI cable, and partly because there won't be any content or displays to support it for a while. However, some firms, such as Cable Matters, have released the latest HDMI 2.1 cables in order to stay ahead of the curve.

What is HDMI ARC, and how does it work?

For better audio, many home theatre installations don't utilise the TV's speakers and instead employ a separate speaker system. Only one issue: how are you expected to utilise that audio configuration without a separate connection if your smart TV generates content via streaming Netflix or Spotify, for example, or by using the built-in tuner? HDMI ARC provides a solution to this problem.

Even while playing material straight from the TV, you may connect an HDMI connection between an audio/video receiver and your TV and still utilise the speakers attached to that receiver.

If you have an external soundbar, HDMI ARC is also useful. You may, for example, connect all of your game consoles, streaming devices, and other devices straight to the TV, then connect the HDMI ARC connection to a sound bar to hear high-quality audio via the soundbar while using all of your devices.

HDMI ARC does not have as much support as it should. While many TV manufacturers have HDMI ARC ports on their sets, such ports don't always support 5.1 surround sound, so that might be why you're having problems integrating surround sound using an HDMI ARC port.

Is DisplayPort preferable than HDMI?

HDMI isn't the only standard that combines video and audio channels into a single cable. Another standard is DisplayPort. Is DisplayPort, on the other hand, superior than HDMI? That is debatable.

DisplayPort 1.4, which enables up to an 8K resolution at 60Hz with HDR, is presently available. DisplayPort is much more prevalent on computer monitors and PCs than on TVs and other consumer electronics, and with good reason: it supports AMD's FreeSync and Nvidia's G-Sync, which assist produce a tear-free gaming experience. Unfortunately, just a few manufacturers are implementing DisplayPort 1.4, while the most are still utilising DisplayPort 1.2. If you only have access to an HDMI 2.0 or DisplayPort 1.2 connector, as many displays do, HDMI may be preferable due to its HDR capability. However, if your monitor supports later DisplayPort versions and you're a serious gamer, utilising it through HDMI could be the way to go.
