HDMI 2.1: Ushering in the New Age of Speed and Clarity

If you're an avid gamer or on the cusp of buying an 8K TV, it's inevitable that you're searching for the best HDMI 2.1 cable to amplify every fine detail. HDMI 2.1 signifies an enormous stride in bandwidth capacity, offering superior resolution, swift refresh rates, dynamic HDR, and auto low latency mode. Imagine clearer music, sharper streaming series, and enhanced gaming graphics – this is the magic of HDMI 2.1.


The Ultra High-Speed HDMI cables, supporting HDMI 2.1, represent some of the most dramatic advancements in HDMI standards to date. If you've acquired a state-of-the-art 8K TV or gaming console, HDMI 2.1 becomes an indispensable component. Embrace the emerging generation today with top-grade cables.

What are the applications of HDMI 2.1 cables?

HDMI (high-definition multimedia interface) cables are the amazing cords that bring your entertainment centre to life. They are the conduit that connects your content source, such as a gaming console or streaming device, and your TV or monitor. None of our high definition TVs or sound systems would be nearly as epic without the humble HDMI.

Now that our TVs and gaming consoles are levelling up, it’s time to level up the cables connecting them. A cable that supports HDMI 2.1 is the best choice if you’re looking to unlock the full graphic capabilities of your Xbox Series X, PS5 or new 8K TV. Otherwise, it’s a little like ordering an expensive meal and having it delivered to your house by someone who stops for coffee on the way – still good, but think of what the experience could have been!

What are the primary distinctions between HDMI 2.1 and 2.0?

Several engaging features, including Dynamic HDR, eARC, Quick Media Switching and auto low latency mode, set HDMI 2.1 apart in the HDMI 2.0 vs 2.1 comparison. HDMI 2.1 also supports superior bandwidth capacity. Based on your cable choice, the new HDMI standard can accommodate nearly three times the data volume through the cable simultaneously, from 18 Gbps with HDMI 2.0 to a remarkable 48Gbps.

While HDMI 2.0 supports 4K resolution up to 60Hz, HDMI 2.1 supports 4K at 120Hz and 8K at 60Hz. This difference may not be noticeable on an older TV, but it's definitely perceivable on an 8K TV or a new gaming system.

Game Mode VRR, another compelling feature supported by HDMI 2.1, uses Variable Refresh Rate (VRR) technology. This allows the content source and display to maintain a perfect 1:1 sync across a frequency range, thus minimising blur and input lag. Who's ready for a smoother gaming experience?

When should I replace my HDMI cables with HDMI 2.1?

A prevalent question regarding the new HDMI standard is, "Do I need to update all my HDMI cables?" This largely depends on your equipment and setup. If you're outfitting your brand-new 8K home theatre, then you're undoubtedly going to want cables that support HDMI 2.1. Opt for this cable type if:

  • You're experiencing intermittent flashing or flickering with your 4K streaming device, such as Apple 4K TV, Google Chromecast Ultra, or Roku.
  • You're playing games in 4K or 8K.
  • You're working with a video-editing workstation that supports 8K resolution.
  • You're streaming audio that uses the HDMI-eARC standard, such as DTS Master, DTS:X, Dolby TrueHD or Dolby Atmos.

Arguably the best part of all is that HDMI 2.1 will cater to a whole range of technologies and products that haven't hit the market yet, making it a judicious investment to procure the finest HDMI 2.1 standard cable available.

Will your new cable be compatible with an older TV or content source? Absolutely. It's noteworthy that HDMI 2.1 cables are backwards-compatible and can function with devices that don't support 8K, giving you the confidence that your new cable will be relevant for many more years.

What does 'Ultra High-Speed HDMI' signify?

Ultra High-Speed HDMI is the formal designation for cables that meet and support the fresh HDMI 2.1 standard, as defined by the HDMI Forum. While the older Premium High-Speed HDMI cables could support a maximum bandwidth of 18Gbps and 4K resolution up to 60Hz, the new Ultra High-Speed HDMI cables can support a maximum bandwidth of 48Gbps and uncompressed 8K resolution at up to 60hz. They also come with very low EMI, or electro-magnetic interference, which leads to less interference with nearby wireless devices.

Ultra High-Speed HDMI cables must undergo testing and receive certification for meeting strict specifications that ensure they can support HDMI 2.1 features including 4Kp50/60/100/120 and 8Kp50/60 video, HDR, VRR and eARC.

What does this mean for your video, audio and gaming? Whether you're trying to maximise your 4K system or unleash the full graphic prowess of 8K devices, you can anticipate faster, more fluid playback and the fastest refresh rates possible with a high-quality Ultra High-Speed HDMI cable.

What makes a high-quality HDMI 2.1 cable? What to focus on when buying.

When the time comes to upgrade your equipment or home theatre system, you'll undoubtedly be looking for the best 4K HDMI 2.1 cable available. A few critical considerations can assist you in making the correct purchase.

Choose the correct length for your Ultra High-Speed HDMI cable
Cable length is vital, as an overly long HDMI cable could lead to subpar signal quality. It's crucial to order a cable that suits a specific setup rather than simply opting for the longest cable. Make sure to measure the distance between your streaming or gaming devices and your TV or monitor when purchasing, so you'll have sufficient cable to span the distance with a bit of extra length. We supply Ultra High-Speed HDMI cables in 0.5m, 1m, 1.5m, and 2m lengths at our store.

Consider the construction quality of any Ultra High-Speed HDMI cable
Materials and construction quality are equally significant as not all cables are created equal. Our cables feature gold-plated connectors resistant to corrosion, ensuring a long lifespan for your cables and electronic equipment. They also have oxygen-free 30AWG and full shielding to minimise noise and distortion. Generic or non-branded cables might not provide these features. When weighing up HDMI 2.1 cable price versus quality, always opt for quality.

We understand your eagerness to receive your order when selecting the best 2.1 HDMI cable for your audio, video, and gaming setups. We dispatch most in-stock orders on the same day.
