Reference HDMI represents the pinnacle of achievement for QED HDMI cables benefiting from the application of design secrets uncovered by our state-of the-art HDMI test suite. Using QED's unique Band Pass FilterTM technology, Reference HDMI delivers high speed digital signals with ultra low jitter for the most accurate timing of picture data available.
It supports Deep Colour, 3D and 4K whilst greatly exceeding the requirements of the latest HDMI 2.0 specification. Here at QED we are so proud of the level of quality and performance achieved by our cables that we offer a lifetime guarantee against manufacturing defects.
AWARD WINNING HERITAGE
New Reference HDMI represents the pinnacle of achievement for QED HDMI cables benefiting as it does from the application of design secrets uncovered by our state-of the-art HDMI test suite and in-depth knowledge of our experienced engineers.
FULL 4K, 3D, FULL HD 2.0 COMPLIANT
The HDMI Authorised Test Centre measurement for High Speed HDMI is taken at 10.2 Gb/s but QED Reference HDMI has been independently tested in our laboratories at a staggering 21.9 Gb/s using a pseudo-random bit pattern test. This gives the cable nearly five times the capacity required for a Full HD or 3D picture providing an enormous amount of headroom!
INDIVIDUALLY SCREENED TMDS PAIRS
Provides improved interference immunity and protects delicate signals from outside interference for enhanced signal integrity and quality.
AN ALL NEW FLEXIBLE CORDAGE!
Band-pass Filter TechnologyTM allows Reference HDMI to utilise an all new thinner cordage with improved flexibility and minimum bend radius enabling it to be used in tight spaces between the TV or projector and the wall.
BAND PASS FILTER TECHNOLOGYTM
Reference HDMI incorporates a built-in passive bandpass filter which must be sited at the TV end - making the cable directional. This filter effectively removes components of the signal above and below the HDMI band pass frequency which can contribute to unwanted timing errors, known as 'jitter'. The filter is also optimised to ensure the signal level does not drop below the predefined amplitude specified by the HDMI governing body. This has the effect of reducing cable induced timing errors, to half that found in a typical branded cable of the same length and specification.

QED Lifetime Guarantee
QED is the only UK manufacturer able to test HDMI cable designs beyond the scope of the current HDMI specification, which means it is uniquely placed to evaluate new technical innovations before deciding whether or not to introduce them into full production. QED has identified cable induced timing error, termed ‘jitter’, as one of the key differentiators between satisfactory and outstanding cables.
|These findings have enabled us to optimise transmission speed and jitter performance to ensure that both exceed the high standards we set for our Reference cable range.|
Naturally, because QED customers demand better, we have scientifically designed our cables to reduce jitter to the absolute minimum.

HDMI HIGH SPEED WITH ETHERNET
Applies to any HDMI cable that has been tested at an authorised test centre and has been found to pass the eye mask test at a combined data rate of 10.2Gb/s 340Mhz pixel clock. The cable must also have passed testing of the CEC and DDC connectivity and be compliant with HDMI Ethernet and Audio Return Channel test procedure.
3D & 4K COMPATIBLE
3D = compatible with 3D TVs; cable has a minimum bit rate of 4.45 Gb/s
1080p Full HD = a video resolution with a bit rate of 4.45 Gb/s
4K = Highest native video resolution offered by HDMI 1.4b; 4096×2160p24 36 bit/px = bit rate 8.03 Gb/s
High Speed with Ethernet = 10.2Gb/s so any High Speed Cable supports all these resolutions
BAND PASS FILTER™ TECHNOLOGY
Incorporates electronics to apply a passive equalization network designed to improve the High Speed jitter performance of the cable. The signal is filtered to remove unwanted components of the signal above and below the required frequency band. Used to convert a low jitter cordage to an ultra low jitter one.
ULTRA LOW JITTER
Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying ultra low jitter has been measured at
