What is the difference between a Standard HDMI cable and a High-Speed HDMI cable?

    Standard HDMI® cables (also referred to as category 1) have been tested by the HDMI Licensing, LLC to perform at speeds of 75Mhz. This is the equivalent of a 1080i signal.

    High-Speed HDMI cables (also referred to as category 2) have been tested by the HDMI Licensing, LLC to perform at speeds of 340Mhz, which is the highest bandwidth currently available over an HDMI cable, making them able to successfully handle 1080p signals. High-Speed HDMI cables also are able to accommodate higher resolution displays, such as WQXGA cinema monitors.
