The Mini-VGA connector is used on laptops and other systems in place of the standard VGA connector. Apart from its compact form, mini-VGA ports have the added ability to output both composite and S-Video in addition to VGA signals through the use of EDID.
The mini-DVI and Mini DisplayPort connectors have largely replaced mini-VGA. Mini-VGA connectors are most commonly seen on Apple's iBooks, eMacs, early PowerBooks (12 inch), and some iMacs, but has also been included on several laptops manufactured by Sony.
The mini-VGA connector can also be used for video output. In this mode, S-Video chrominance (C) and luminance (Y) signals replace the red and green channels, while an equivalent composite video signal is output on the blue channel. The horizontal and vertical sync pins are unused.
