Tripp Lite's 3-ft. HDMI (High-Definition Multimedia Interface) Gold Digital Video Cable allows interconnection between digital display devices, such as DTV's (Digital Television), Plasma displays, LCD TV's and projectors, to Digital source devices, such as Digital Set-Top boxes, DVD/DVD-R players and AV receivers. HDMI assures that the best video signal is always sent from the source (HDTV signal, DVD Player) to the display (Projection Television or Plasma). It does this by allowing uncompressed video and multi-channel audio data to be input to the display device through one single cable. The need for multiple analog connections for high-resolution audio and video are eliminated. Without a HDMI connection, you would need 3 video connections for high-definition video and 6 audio connections for high-resolution audio.
