Apple,[1] HP,[2] and Asus[3] each introduced separate connectors using the same moniker of "mini-VGA", but which are otherwise physically incompatible with each other (though all of them are compatible with standard VGA using the correct adapter).

When used for S-Video, S-Video's chrominance (C) and luminance (Y) signals replace VGA's red (R) and green (G) channels, while for composite video, the signal is output through VGA's blue (B) channel.

(The horizontal and vertical sync pins of VGA are left unused.)

Samsung Chromebooks, as released in June 2011, feature their own implementation of mini-VGA.

[5] Mini-VGA ports can also be found on several laptops previously manufactured by Sony.
