There have been many improvements to HDMI over the years since. Extra features are added as the needs of TVs have changed and HDMI 2.1 is the next big step. This is the AV world's workhorse. High Speed HDMI cables can manage any device or content all the way up to video with 4K resolution at 30Hz. 3D video, deep color, and, of course, 1080p HD are all supported. Static HDR (like HDR10) will work, too, although we don't recommend this kind of cable if you want to experience Dolby Vision HDR. As a dynamic version of HDR, it uses a lot more data and thus benefits from a faster cable. Below you’ll find our guide to everything you need to know about HDMI 2.1 and all of the changes that have arrived with this new HDMI standard that is already shaking up TV, movies and gaming for the better. The current implementation of ARC has some limitations, though; the lowbandwidth (~1 Mbps) limits the quality of the audio that can be sent over the return channel, making it impossible to send high quality, uncompressed audio to your receiver. eARC solves these issues, as long as you have a compatible receiver as well. It vastly increases the amount of bandwidth that the ARC channel can use, up to an impressive 37 Mbps. This extra bandwidth makes it possible to send uncompressed 5.1 and 7.1 audio, like Dolby TrueHD and DTS-HD MA, which are often the carrier signals for Dolby Atmos and DTS:X. When it comes to Samsung, you'll find HMDI 2.1 in a handful of sets from last year, which includes the Samsung QN85A, and Samsung QN90A Neo QLED TV. But again, HDMI 2.1 will be available in more of Samsung's TVs for 2022.
The increased bandwidth supported by HDMI 2.1 allows TV manufacturers to release new devices with resolutions as high as 10k (10420x4320). It's not likely that displays with these ultra-high resolutions will be available on the market for many years. However, the main advantage of having HDMI 2.1 support on a 4k TV is that it cansupport 4k @ 120Hz content, which is what the newer gaming consoles output. HDMI 2.1 increases the maximum uncompressed bandwidth that an HDMI cable can handle up to 48 Gbps, and the maximum compressed bandwidth to at least 128 Gbps. While this is the maximum bandwidththe cable can handle, it may be some time before devicesneed that much bandwidth, and manufacturers can create TVs that support less bandwidth. For example, if a TV manufacturer only wishes to support 4k @ 120Hz, with 4:2:0 chroma subsampling, then they only need to support about 32 Gbps, and it can still be considered anHDMI 2.1 device. This gives manufacturers significantly more flexibility and allows them to save costs, as they don't need to implement support for the extra bandwidth that the device can't use- a 4k TV doesn't need 8k bandwidth. As well as making the ideal HDMI cable for 8K TVs, the QED Performance Ultra High Speed HDMI suits the latest games consoles. Supporting 4K@120Hz and Dynamic HDR technology, this cable is the one you need to make the most of the latest games. Another example is eARC, which can be added to almost any HDMI 2.0 device with a firmware update. Some HDMI 2.0 TVs have eARC support, includingthe entry-level Vizio V Series 2020. Once again, these devices support features from HDMI 2.1 but aren't HDMI 2.1 sources. Q: Will I need to upgrade my cables? The perfect partner for 8K TVs and the latest games consoles, the QED Performance Ultra High Speed HDMI 3m cable is where Ultra High Speed connectivity begins.
With the introduction of the HDMI 2.1 standard in 2018 the maximum data rate of the HDMI link increased from 16 Gb/s of the previous Premium cable standard (HDMI 2.0) to 48 Gb/s. This was to accommodate the new uncompressed 8K@60Hz video standard (termed 8K60 4:2:0). With our high end USB A-B we isolate the power and data conductors preventing any potential cross talk, therefore meaning less jitter and an enhanced audio performance. Next to the trusty USB cable, HDMI cables are just about the most useful cable in home entertainment setups across the globe. They connect everything from TVs, Blu-ray players, and streaming devices to gaming consoles, AV receivers, and speakers.
The Ultra High Speed HDMI Certification Program is a mandatory certification program for all Ultra High Speed HDMI Cables; and ensures quality Ultra High Speed HDMI Cables reach the market and support 4K and 8K video, HDR, VRR, eARC, and all other HDMI 2.1b features. Cables are also required to be tested and certified to ensure low EMI to reduce the possibility of interference with wireless networks, streaming media players, Bluetooth devices and mobile phones. This is a fully certified and compliant cable, that adheres to all the requirements necessary to be recognised by HDMI. There are a tonne of support features including ALLM, VRR, and Dynamic HDR as well as many others. Take a look at the breakdown of screen tear, to understand why these features are so helpful. Gamers can also make the most of variable refresh rate (VRR) technology now possible with HDMI 2.1. This protects against screen tearing, which occurs when the refresh rate of your monitor or TV is out of sync with the one provided by your console or gaming PC. The result of this is temporary image jitters or freezes that can affect immersion and gaming performance. VRR stops this by varying the frame rate of the monitor or TV to match its input. If you pair this with one of the best HDMI 2.1 monitors you can be sure it’ll be compatible with the same technology. As reported by Ars Technica in late 2021, many HDMI 2.1 capable devices might not actually have these high-end features after all. Apparently that's thanks to a quirk in the official HDMI guidelines – it turns out that the spec for HDMI 2.0 has been wholly replaced by HDMI 2.1, instead of simply building upon it.

For the last few generations, HDMI cables have had an Audio Return Channel (ARC), which means audio can be sent both ways between a TV and audio gear. This essentially enables a display to send its own audio – perhaps from a built-in Netflix app – to a soundbar or surround sound system, bypassing its own speakers. The most common type of cable used for connecting products on a wired network. This cable connects wired devices together to the local network for file sharing and Internet access. SUBWOOFER CABLE
