RGB (D-sub 15-pin) jack
Found on some HDTV-ready TVs and HDTV tuner boxes, RGB connections are used for transferring video signals, including high-definition content. As implied by its name, RGB sends the red, green, and blue components of the video signal along separate paths.
Though RGB connections can take a number of forms, one that's increasingly common on TVs and set-top boxes is the D-sub 15-pin jack. If you own a computer, D-sub 15-pin connections may look familiar — they're the same ones found on standard VGA-type computer monitors. RGB connections pass video signals in the analog domain.
