HDMI High Speed with Ethernet cable is the newest and best iteration of HDMI cords that will provide you with all the features of your brand new HDTV including 3D, 1080p and above, surround sound audio and many others. This new feature further delivers on HDMI promise to reduce cable clutter between your devices. As more and more devices become "connected" devices, taking advantage of features like streaming video over YouTube and NetFlix, rather than buying a new router and stringing Ethernet cables to each of these devices, your television can act as a type of router connecting to the internet through a single Ethernet connection and distributing connectivity to each of your other devices through the same HDMI cable that's transmitting video and audio content.

Audio Return Channel - Send audio data "upstream" to a surround audio system, eliminating the need for a separate audio cable. 3D - Defines input/output protocols for major 3D video formats, paving the way for true 3D gaming and 3D home theater applications. 4K Support - Enables video resolutions far beyond 1080p. Additional Color Spaces - Adds support for additional color models used in digital photography and computer graphics.
