QED is proud to present the new Performance Active HDMI cable designed specifically for use at High Speed over cable runs up to 15 metres in length.
A brand new design concept from QED which utilises QED 'Active Filter Technology'TM delivering high speed up to and including 15m. Until now it has been difficult to achieve support for 3D, Deep Colour or 4K video resolution over the long distances required for modern high performance projectors. It is often necessary to employ expensive booster boxes which require external power supplies or use cables with a difficult to hide "electronic bulge" inconveniently situated half way along. QED Performance Active HDMI changes all that by introducing Active Filter Technology(TM). A dedicated integrated circuit especially developed to provide High Speed data performance over long cable runs is built unobtrusively into the head shell of each cable.
Independently tested to deliver High Speed w/Ethernet and exceed the requirements of the latest HDMI specification. Supports Full HD, 3D, 4K and Deep Colour.
Performance Active HDMI measures at less than 50ps of jitter, significantly reducing the incidence of bit errors reaching the TV and maximising the audio and video data transfer.
99.999% Oxygen Free Copper conductors
Supports 4k x 2k Resolution
QED is one of the only UK manufacturers 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.
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 very low jitter has been measured at
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 = 4K native video resolution offered by QED HDMI 2.0; 4K@60Hz= bit rate 18 Gb/s
High Speed with Ethernet = 10.2Gb/s so any High Speed Cable supports all these resolutions
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.
Incorporates electronics that can measure performance of the twisted pairs in the cable and apply an appropriate active equalization network designed to extend the High Speed performance of the cable to 15m. The signal is filtered to remove unwanted components of the signal above and below the required frequency band and the remaining signal is amplified to the original level.
