FIRST TIME USE REAR PANEL JACKS ቧ HDMI1 (High Definition Multimedia Interface) (INPUT 1) About HDMI HDMI is the next-generation all digital interface for consumer electronics. HDMI enables the secure distribution of uncompressed high-definition video and multi-channel audio in a single cable. Because digital television (DTV) signals remain in digital format, HDMI assures that pristine high-definition images retain the highest video quality from the source all the way to your television screen. Use the HDMI input for your external devices such as Set-Top-Boxes or DVD players equipped with an HDMI output connection. HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI Licensing LLC. NOTES: 1.
