VGA is the traditional connector used to connect your PC to video monitors. It is also one option to connect your PC to videoprojectors and HDTV sets. This connection offers a better video quality compared to component video, S-Video and composite video because it uses an independent wire for each video signal: red, green, blue, horizontal sync and vertical sync. It uses a 15-pin connector known as D-Sub, D-Shell or HD15. On this connection information is transmitted using analog signals, while on DVI and HDMI information is transmitted digitally, thus providing a better quality. So if your video monitor, videoprojector or HDTV set has a DVI or HDMI connector – which will be the case with current models available on the market – you should use one of them instead of the traditional VGA connector to connect your PC to your monitor, projector or HDTV.
