QED’s new Performance Ultra High Speed HDMI 2.1 cable supports full 8K video content

British audio specialists QED introduces the Performance Ultra High Speed HDMI 2.1 cable, designed to handle high-quality, uncompressed 8K video at up to 60 frames per second. Succeeding the company’s Performance Premium range of digital cables and remaining at the same price, this single HDMI 2.1 cable is an affordable, top-quality proposition for all dedicated home cinema enthusiasts.

QED has been designing and engineering superior analogue and digital cables for more than 45 years, and its new Performance Ultra High Speed HDMI 2.1 cable is informed by the results of the company’s exhaustive research into cable design since 1995.

Supporting the latest HDMI 2.1 standard, this new specification defines the fastest copper-based data rate ever conceived, raising the maximum throughput from 16 Gb/s of the previous Premium cable standard (HDMI 2.0) to 48 Gb/s to support uncompressed video resolutions of up to 8K@60Hz (4:2:0) with 12bit HDR. The cable will also carry uncompressed 4K@120Hz video, while delivering the promised maximum compressed video resolution of up to 10K@120Hz. Lastly, Dynamic HDR* and Enhanced Audio Return Channel (eARC), are also supported no matter what brand or combination of HDMI 2.1 compatible equipment you are using.

QED Ultra High Speed HDMI cables have to undergo stringent mandatory testing at an HDMI Forum Authorized Testing Centre, not only to establish compatibility with the new 2.1 video standards, but also to ensure low levels of electromagnetic radiation, to reduce the possibility of interference with wireless networks, streaming media players, Bluetooth devices and mobile phones. This is realised through QED’s Triple-shielding design that further protects against interference for optimal signal quality.

QED is one of the first brands to officially adopt the new cable category in the form of the new Performance Ultra High Speed range. The cables have received the official stamp of approval from the HDMI Forum accredited laboratory in the form of the instantly recognizable Ultra High Speed Certification Program stickers. Just scan the QR code on the label using the official HDMI app to be reassured that the cable is a genuine QED Ultra Speed HDMI cable.

All the cables are completely backward compatible with HDMI 2.0b and 1.4b standards and are available in 1.5 and 3 metre lengths, which will ensure continued years of upgradeable video enjoyment at home.

The QED Performance Ultra High Speed HDMI Cable is available now, priced:

  • £29.95/€ 36.00/$39.95 - 1.5m
  • £39.95/€ 48.00/$59.95 - 3m

*High Dynamic Range (HDR) support was introduced with HDMI version 2.0. With HDR-compatible TVs and equipment there is a greater contrast ratio and more brightness steps to give a smoother picture and more detail in both bright and shadowy areas. A related technology usually associated with HDR is Wide Colour Gamut (WCG), which offers an expanded colour palette.
