HDMI supports 4K (2160p) up to 60fps. This allows full-resolution 4K 3D, along with higher-frame-rate 2D content, like home videos and computer games for PC. Bandwidth HDMI increases the size of the pipe transmitting data from the source to display. This makes possible the increased frame rates at high resolutions. It also allows even more interesting lower-resolution images. HDMI supports dual video streams. There's also support for a 21:9 aspect ratio.Notes:We manufacture High Speed HDMI Cables with Ethernet. In accordance with HDMI rules, our cables are marketed in this manner with "High Speed HDMI Cable with Ethernet" marked on each cable jacket.Installing a cable supporting HDMI features does not necessarily give your existing devices with previous HDMI specifications the ability to experience 4K resolution, 3D, audio return or Ethernet. The latest equipment supporting these desired HDMI features is required.HDMI cables are not hot-pluggable or hot-swappable for all devices. Especially with PCs and projectors, you must first power off the devices completely, then plug in each new cable, then power on. This enables the devices to learn the encoding in the cable and function properly and to your device's fullest potential.
