HDMI (High Definition Multimedia Interface) is a specification that combines video and audio into a single digital interface for use with DVD players, digital television (DTV) players, set-top boxes, and other audio visual devices. HDMI supports standard, enhanced, or high-definition video plus standard to multi-channel surround-sound audio. Our cables are HDMI male to male that connect a HD device such as a Blu-Ray player to a HD display screen.
