How Can You Tell What Type of Hdmi Cable You Have

Since HDMI sockets and cables first appeared in 2002, they haven't half caused some problem. They've been responsible, for instance, for generations of AV equipment going all of a sudden and unceremoniously out of appointment. They've led to untold numbers of cable breakages due to their flimsy attachments.

Unlike HDMI sockets on different devices take bamboozled consumers past supporting different features. People trying to run long HDMI cable runs accept sometimes found they get no motion-picture show.

Last but not to the lowest degree, ever increasing information demands placed on HDMI cables ways they now come in three different grades that you actually need to take at to the lowest degree a rudimentary understanding of, especially if you lot want to make the nearly of your AV equipment in 2022, with the likes of the PS5, Xbox One Series X and the latest 4K UHD smart TVs all having unlike demands when it comes to using the right HDMI cable.

Despite all these issues, though, HDMI connections take endured. Mostly because for all their issues, they've remained almost endlessly upgradable, keeping stride with not just the demands of the AV globe simply, equally we'll see, the world of the smart home, besides.

Information technology's also true, of course, that HDMI cables were designed with the all-time of intentions: to provide a single-cable digital video and audio solution.

Nevertheless, it'southward clear that plenty of HDMI nonsense has happened along the manner. So here we endeavor to selection through the HDMI myths to provide only the facts that you actually need to know and aid you cull the best HDMI cablevision, whether it's for your gaming console, cablevision box, AV receiver, soundbar, or whatever else you lot want to plug into your TV.

Why aren't all HDMI connections the same?

HDMI ports deal in digital data. And since the demands placed on digital data modify much faster than things did in the analog age, HDMI connections and cables keep having to evolve too.

So chop-chop has HDMI had to accommodate, in fact, that at that place a number of unlike generations of HDMI port are simultaneously playing a primal function in today'due south AV world. In fact, sometimes a single product tin deport multiple generations of HDMI.

The primary HDMI generations you demand to concern yourself with if you're thinking of buying a new AV product now are v1.4, v2.0, and v2.one. Let's look at each in plough.

HDMI V1.iv

HDMI v1.4 was a big bargain when it debuted in 2009 because it was the outset HDMI platform with plenty information bandwidth for 4K moving picture resolutions. It can, though, only shift enough information to support 4K at up to 30 frames a 2d.

Similarly, while it supports loftier dynamic range playback, that support is restricted with 4K to 8-bit color quality, rather than the ten or 12 chip support offered by later HDMI versions.

Many devices (such equally cable boxes, the original PS4, most projectors and many relatively affordable TVs) still carry these relatively affordable ports.

HDMI v1.4 likewise introduced the HDMI Ethernet Aqueduct (HEC). This allows two connected devices to share a wired Net connexion - potentially very handy for smart domicile installations.

Finally, v1.4 HDMIs support Audio Return Channel technology, which enables HDMI ports and cables to be used equally both an AV input and an audio output.

And then yous tin apply an HDMI port to, say, pass a digital sound rails out from a Idiot box to an external ARC-capable audio device such as a soundbar (the Sonos Arc, for example) or AV receiver, even if that HDMI port is as well receiving video and sound.

HDMI V2.0

The v2.0 HDMI provides much more bandwidth - importantly so that it can better handle 4K video.

Its 18.0 gigabits per 2d throughput is enough to support 4K at frame rates of upwards to 60Hz, as well as loftier dynamic range video up to the broad 'Rec 2020' color space with 10/12-bits of colour resolution.

As well introduced with HDMI 2.0 is back up for upward to 32 audio channels at a high 1536kHz sampling frequency, and as many every bit 4 simultaneous audio streams and two simultaneous video streams.

HDMI 2.0b additionally added playback of the new Hybrid Log Gamma format already used by the BBC and expected to exist taken up by other broadcasters soon.

Since 2019, one or 2 brands have been able to squeeze one or two features associated with the HDMI ii.1 standard we're coming to adjacent into HDMI 2.0 bandwidths. Sony, for instance, has managed to get eARC lossless sound engineering working over HDMI ii.0 (see the HDMI two.one section for more on this), while Samsung has managed to back up the AMD Freesync variable refresh rate gaming system without needing a 2.1 HDMI port.

This has led to some confusion over the usual HDMI naming/numbering conventions, with essentially two.0 HDMIs getting referred to in terms of HDMI 2.one features they might back up.

HDMI V2.1

Formally launched on November 28 2017, the v2.1 HDMI is the unmarried biggest step frontwards for HDMI technology to engagement, with its massively increased 48Gbps maximum data rate opening up the potential for exceptional picture and sound quality, as well every bit innovative new features.

Unfortunately, though, it has also get by far the most complicated HDMI generation to date, cheers to a combination of displays 'running ahead' with some 2.1 features and claims before they've been fully ratified, and the potential for HDMIs of widely differing specs to be called HDMI 2.1.

Looking at the sort of new features HDMI 2.1 supports, every bit well as handling 4K images at frame rates of up to 120Hz, it can play video resolutions of up to 10K at lower frame rates (including 8K at 60Hz), paving the way for the adjacent generation of 8K-resolution TVs.

It likewise supports then-called Dynamic HDR, where extra scene by scene information is provided to displays to assist them show their HDR pictures better. Though dynamic HDR technologies such as Dolby Vision and HDR10+ have already been available via some HDMI two.0 and even (in Dolby Vision's case) HDMI 1.4 connections.

HDMI ii.1 introduces some fundamental gaming features, such as variable refresh rate support to tackle prototype lag, stuttering and frame tearing; quick frame transport to help screens display images faster; and an Automatic Low Latency Mode feature that can trigger displays to automatically switch into their fast-response game modes when a game is detected.

These features are all expected to be supported by the the latest gaming consoles such equally the PS5 and Xbox Serial X, and accept actually already arrived on Nvidia's RTX xxx graphics cards.

HDMI two.1 also improves the HDMI Audio Return Aqueduct feature. Its 'eARC' version supports bandwidths big enough to carry lossless (uncompressed) object based sound formats, such every bit the purest versions of Dolby Atmos and DTS:10 carried on Blu-ray and 4K Blu-ray discs.

The trouble with HDMI 2.1 is that its implementation has become very fragmented between different displays, with different TVs and TV brands claiming support for diverse HDMI 2.1 features, rather than anybody just using a unmarried HDMI 2.1 standard that covers ALL HDMI two.1'due south potential capabilities.

Much of this potential confusion is downward to manufacturers deciding to support different data rates with their various HDMIs, where the data rate tin dictate the level of HDMI ii.1 features that tin can be supported.

The outcome of this is that yous if y'all see a Goggle box claiming to carry i or more HDMI 2.1 sockets (it's common, but to confuse you more than, for TVs to comport unlike HDMI 'generations'), don't assume that it will necessarily provide all the features HDMI ii.1 is capable of. Look for some sort of itemised breakdown of which specific HDMI 2.1 features it can deliver.

HDMI Overlap

Every bit noted in passing while looking at each HDMI generation, there tin can be some characteristic fluidity betwixt HDMI generations. For instance, the Dolby Vision dynamic HDR system has actually worked on every HDMI since v1.4.

Samsung has managed to get some HDMI 2.ane features (auto game mode, variable refresh rate support, support for other non-Dolby dynamic HDR formats) working on its current HDMI 2.0 Boob tube connections. And Sony has been offering eARC support over HDMI 2.0 since 2019.

HDMI and CEC

One potentially useful trick of HDMI cables for smart home applications is CEC. Short for Consumer Electronics Control, CEC lets you control multiple devices connected via HDMI using merely one remote command. So, for example, if yous connect a CEC-enabled Blu-ray actor to a CEC-enabled TV, you will get actress card options that let you lot use your TV remote to command Blu-ray playback.

Since the arrival of HDMI ii.0, CEC has had the potential to drive up to fifteen devices via a single remote control.

CEC can currently exist clunkily implemented or hard to follow on many devices, though - and many consumers don't even know it exists. A concerted industry-wide push of CEC engineering science would probable aid CEC realise its total smart home potential.

HDMI cables: What you demand to know

As with HDMI connections, different HDMI cables tin can carry different amounts of data. And then if you just buy the cheapest HDMI cable you lot can observe, information technology may not give you all the features you want. For example, if an HDMI cable can't carry at least 40Gbps of data, it won't be able to support 4K at 120Hz gaming.

To attempt and make life easier, the HDMI.org has established 3 HDMI 'standards' for you to wait out for when trying to buy an HDMI cable.

Bones 'category 1' HDMI cables are not designed to carry the 18Gbps data rates associated with today's HDMI 2.0 4K/HDR connectivity. Equally a result, while they can cost mere pennies, they're probably best avoided now if you have whatsoever interest in 4K/HDR moving-picture show quality, or HDMI's latest CEC 'smart domicile' capabilities.

Category 2 HDMI cables - besides known equally High Speed HDMI cables - are designed to handle the 18Gbps required to unlock HDMI v2.0 features. Category 2/High Speed cables should exist labelled as such on their retail information.

The newest HDMI 2.1 format depends on data rates far higher than HDMI 2.0's 18Gbps. In fact, it needs equally much as 48Gbps. So to cater for this you'll need what's called an Ultra High Speed HDMI cable capable of handling such huge amounts of data.

Should you buy Premium Certified/Ultra Certified HDMI cables?

While all HDMI cables should tell you lot at point of retail whether they are bones, High Speed or Ultra Loftier Speed cables, that doesn't mean that they've all been formally assessed by the HDMI Licensing group every bit definitely delivering all the features they promise. In fact, the vast majority volition not take received official certification.

Uncertified High Speed and Ultra High Speed cables should all work fine, to be clear - but if you want absolute 100% peace of mind, you could look out for cables that have officially passed the official High Speed and Ultra High Speed compliance tests established by HDMI Licensing.

Looking out for officially certified cables is particularly recommended if you need a relatively long cable run (5m or more).

The 'Premium Certified' badge for HDMI cables was created by the HDMI Licensing Group to testify that a cable has passed the organisation's internal 18Gbps tests. The Ultra Certified Cable badge was created to show where a cable has passed the system's internal 48Gbps tests.

Officially certified cables are immune to show the HDMI Licensing group's certification logo, complete with QR lawmaking, at point of retail (such as on their Amazon web pages).

Notation that while Premium Certified cables have been widely available for some time, it was only in September 2022 that the first Ultra High Speed HDMI cable was officially certified - the best part of three years after the first Ultra Loftier Speed HDMI cables went on sale.

What are Agile HDMI cables?

Most HDMI cables are passive, and can pass their signals in either direction. Active HDMI cables, though, merely send their video point in one direction. Why? Because they contain power boosters that amplify the signal coming from your source equally they ship it on its way.

For most HDMI cable runs an active HDMI cable won't be necessary. All the same, if you lot demand to use a really long cable run (probable 30 feet or more), an Active HDMI cable may make the difference betwixt a data-intensive point making it or non, as HDMI cables by and large become less reliable the longer they are.

Active HDMI cables are potentially more likely to be useful for smart abode applications based on CEC applied science than typical video set ups.

Are expensive HDMI cables worth it?

You lot can spend thousands of pounds even on quite brusk HDMI cables. Simply there'due south doesn't seem to be any compelling reason to do and then.

Unlike the analogue world, where higher quality analogue cables can deliver superior audio or motion-picture show results, HDMI's digital nature substantially means that cables either conduct enough zeroes and ones from one end to the other to deliver a video signal, or they don't.

Some relatively expensive cables can offer handy tricks such as extra-strong mounts, or smart home-friendly apartment cable profiles for running under carpets. Also, if yous've got a very long cable run and a 4K or fifty-fifty 8K screen to feed, information technology is possible that a relatively expensive cablevision will carry all that signal bandwidth more consistently/successfully. Cables that accept received official certification from the HDMI Licensing grouping may cost a little more, too.

None of these premium options, though, demand to cost hundreds or thousands of pounds.
