The v2.0 HDMI provides much more bandwidth - chiefly so that it can better handle 4K video. So you can use an HDMI port to, say, pass a digital audio track out from a TV 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 also receiving video and sound. This allows two connected devices to share a wired Internet connection - potentially very handy for smart home installations.įinally, v1.4 HDMIs support Audio Return Channel technology, which enables HDMI ports and cables to be used as both an AV input and an audio output. HDMI v1.4 also introduced the HDMI Ethernet Channel (HEC). Many devices (such as cable boxes, the original PS4, most projectors and many relatively affordable TVs) still carry these relatively affordable ports. Similarly, while it supports high dynamic range playback, that support is restricted with 4K to 8-bit color quality, rather than the 10 or 12 bit support offered by later HDMI versions. It can, though, only shift enough data to support 4K at up to 30 frames a second. HDMI v1.4 was a big deal when it debuted in 2009 because it was the first HDMI platform with enough data bandwidth for 4K picture resolutions. The main HDMI generations you need to concern yourself with if you’re thinking of buying a new AV product now are v1.4, v2.0, and v2.1. In fact, sometimes a single product can carry multiple generations of HDMI. ![]() So quickly has HDMI had to adapt, in fact, that there a number of different generations of HDMI port are simultaneously playing a key part in today’s AV world. And since the demands placed on digital data change much faster than things did in the analog age, HDMI connections and cables keep having to evolve too. Why aren’t all HDMI connections the same? So here we attempt to pick through the HDMI myths to provide only the facts that you really need to know and help you choose the best HDMI cable, whether it's for your gaming console, cable box, AV receiver, soundbar, or whatever else you want to plug into your TV. Nonetheless, it’s clear that plenty of HDMI nonsense has happened along the way. It’s also true, of course, that HDMI cables were designed with the best of intentions: to provide a single-cable digital video and audio solution. Mostly because for all their issues, they’ve remained almost endlessly upgradable, keeping pace with not just the demands of the AV world but, as we’ll see, the world of the smart home, too. Last but not least, ever increasing data demands placed on HDMI cables means they now come in three different grades that you actually need to have at least a rudimentary understanding of, especially if you want to make the most 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 different demands when it comes to using the right HDMI cable.ĭespite all these issues, though, HDMI connections have endured. People trying to run long HDMI cable runs have sometimes found they get no picture. They’ve led to untold numbers of cable breakages due to their flimsy attachments.ĭifferent HDMI sockets on different devices have bamboozled consumers by supporting different features. They’ve been responsible, for instance, for generations of AV equipment going suddenly and unceremoniously out of date. Since HDMI sockets and cables first appeared in 2002, they haven’t half caused some trouble.
