Will any of the new HDMI 1.4 features require a new cable?
The HDMI Ethernet Channel feature will require a new cable that supports this functionality, either a Standard HDMI Cable with Ethernet or a High Speed HDMI Cable with Ethernet, depending on the maximum resolution to be supported. The Automotive Connection System will also employ a new class of cable, the Standard Automotive HDMI cable, which is designed specifically for automotive use. All of the other new HDMI 1.4 features will be compatible with the existing categories of cables.
