VGA, DVI, S-Video and other video connectors pinouts  > Nvidia pinouts
7 pin video out to three female RCA plugs (red, green, blue). These outputs are for YpbPr (YCbCr), or component, inputs to a TV. Connector can also be used with a standard s-video connector - the 7 pin mini-DIN has the same plastic key feature as the standard 4 pin mini-DIN s-video connector.

The plug on the nVidia video card can output either

1. composite video (using a standard s-video to composite adapter). For NTSC this is standard definition (yellow RCA plug).

2. s-video (4 pin mini-DIN)

3. component (HDTV / YPbPr - the 'red' 'green' blue' video connectors).  These are the analog 'high definition' signals capable of up to 1080p signals.
