The selection of cables on this page used to be referred to as HDMI 1.4 Cables, the naming convention of HDMI Cables has since changed so if you came here to buy what used
to be called an HDMI 1.4 Cable then you should select either high speed or high speed with ethernet as described below. This page is left in place with the old and new names
to explain the new system and clear up the confusion.
HDMI 1.4 introduces new features into equipment such as ethernet channel and audio return, initally due to a change in HDMI cable wiring the cables were referred to as version 1.4 cables (and many still are). Previous HDMI versions (1.0, 1.1, 1.2, 1.3 etc) were all of the same basic construction but tested differently. The term HDMI 1.4 cable is no longer used despite some of the bigger name manufacturers still suppling us cables with it printed on them! These cables are now referred to as high speed or high speed with ethernet, the with ethernet variant has a different construction yet still retains backwards compatibility. High speed with ethernet cables incorporate a fifth shielded twisted pair that is used for ethernet channel and audio return, sometimes referred to as HEAC, HDMI Ethernet and Audio return Channel. The new shielded twisted pair uses the previously unused pin 14 and the Hot Plug Pin 19 with the shield or drain connected to the CEC ground on Pin 17 of the HDMI connector.
The high speed with ethernet cable can be used today with all exisitng HDMI equipment and can be used for the next generation of devices that will transfer data and return audio, it is estimated that 24% of HDMI devices will make use of the new ethernet channel which supports bi-directional 100Mbps data. Futureproof your system today by using a high speed HDMI cable with ethernet.
If you came here to buy an HDMI 1.4 Cable, they don't exist (in name anyway). For 1080p and 3D over HDMI select a high speed cable (although you may find these marked HDMI 1.3 until all the stock in the channel sells through), if you plan to connect web-enabled devices or equipment that supports audio return channel then select high speed with ethernet.
