The two long time standards of the electronic industry are the RBG/VGA connectors. RGB gets its name from the three primary colors, red, green, and blue. These colors are combined to produce the myriad of colors available. An example is 24 bit color, where each of the three has eight variants that can be combined to produce the final color. VGA stands for video graphics array, and is a pin type connector that is used to transmit signals to a display monitor.

The VGA connector comes in two styles, one with nine pins in two rows, and the other with 15 pins in three rows. The 15 pin connector has the capability of carrying HD signals, but the RGB/VGA array has been left behind in the area of video and audio capacity by the new s-video connection, as well as the DVI (digital video interface) and the HDMI (High Definition Multi-media interface) plugs.

The main use of VGA has long been in the area of personal computing. The ability to tie the VGA directly to the motherboard of the PC has made it a standard part of computer connections, and this is likely to remain so for some time. However, there is a trend toward the integration of the PC into the overall Home Theater experience, and this is surely going to lead of more use of the interface type plugs. The increased pixel arrays of the new generation of televisions has led to new ways of producing the color spectrum, and has lead to a decline in the importance and use of the RGB model also.
