HDMI (High Definition Multimedia Interface) is designed for the easy transmission and control of video and - in the case of version 1.4 onwards - network signals. Version 1-1.2 supports 1920×1200 and 24-bit colour depth, version 1.3 adds 2560×1600 resolution and 48-bit colour (Deep Colour) and version 1.4 adds 4096×2160 (4k) resolution and networking. HDMI is backwards compatible with DVI.
Note that as of this writing there isn't much our there that will take advantage of HDMI 1.4 but Kramer do a number of HDMI 1.4 switches and distribution amplifiers.
