High Speed with Ethernet
QED were connecting the Audio Return Channel [ARC] before it was a requirement of the HDMI organisation and since the introduction pf the HDMI 1.4 Specification in 2009, we have focused on only manufacturing the highest standard High Speed with Ethernet cables. This policy of only manufacturing the highest specification HDMI cables enabled us to immediately support the new HDMI 2.0 standard introduced a few years ago and certify our cables for 4K60 use.
With the introduction of the HDMI 2.0 standard in September 2013 the maximum data rate of the HDMI link increased from 10.2Gb/s to 18Gb/s. This was to accommodate the new uncompressed 4K 60Hz video standard [termed 4K60 4:4:4] which required a data rate of 16:06Gb/s. In order to archive this, the source and display equipment at each end of the cable have also to be 2.0 compliant. However the cabling physical layer remained unchanged and this is still the case for version 2.0b introduced in March 2016.
High Dynamic Range [HDR] support was also introduced with HDMI version 2.0b. With HDR equipment there is a greater contrast ratio and more brightness steps to give a smother 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.
Premium Cable Certification Program
Recently, the HDMI.org has introduced a new Premium Cable Certification Program. This is not a new cable category and is addition to the 2.0b specification which has not changed. Premium Certification offers a difficult to counterfeit guarantee label which promises the consumer a minimum standard of performance, In order to continue to provide our customers with a range of cables n which they can have the utmost confidence we are offering Premium certification on the two most popular length cables - 1.5m and 3.0m. This is of course in addition to our usual QED Lifetime Guarantee.
Consumers can scan the unique QR code on the Premium sticker to verify that the cable in their hand is a genuine QED cable, certified to full Premium High Speed 2.0b compliance including support for UHD 4K60, HDR and HDCP 2.2 content protection.
The new cable range has been designed to be as thin and flexible as possible. Gone are the days of large bulky HDMI cables and the new Performance range is characterised by a sleek black livery with a maximum OD of just 6mm to ensure that it is suitable for use with the slimmest TVs.
In reducing the cable the diameter we have not compromised on the purity of the conductors we use, which are still made from 99.999% Oxygen Free Copper.
The new range comes in lengths 1.5m, 3.0m and 5.0m.
