Performance UHD HDMI cables are QED's most flexible yet. Built upon the experience they have gained from designing previous eFlex cables, they have been able to further reduce the diameter of this HDMI cable to improve its flexibility, yet maintain its capability to transmit 4K60 video.
Premium Cable Certification Program
Recently, HDMI.org has introduced a new Premium Cable Certification Program. This is not a new cable category, it is in 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 QED customers with a range of cables in which they can have the utmost confidence QED are offering Premium Certification on the two most popular length cables 1.5m & 3.0m. This is of course in addition to the 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.
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 16.06 Gb/s. In order to achieve 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
QED always connected the Audio Return Channel (ARC) even before it was a requirement of the HDMI organisation and since the introduction of the HDMI 1.4 Specification in 2009, QED have focused only on manufacturing the highest standard ‘High Speed w/ Ethernet ‘cables. This policy has enabled them to immediately support the new HDMI 2.0 standard introduced a few years ago and certify their cables for 4K60 use.
High Dynamic Range
HDR support was also introduced with HDMI version 2.0. 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 Color Gamut (WCG), which offers an expanded colour palette.
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 diameter of just 6mm to ensure that it is suitable for use with the slimmest TVs. In reducing the cable diameter we have not compromised on the purity of the conductors we use, which are still made from 99.999% Oxygen Free Copper.
