VGA Connector cables or VGA to RCA Converter cables. I bet nobody knows what they are or how they are used. The truth is, most of us use them every day if we use a computer, or we connect our computer up to our TV.The 15-pin VGA connector is common to most video cards, computer monitors, and high definition television sets that support VGA-connector devices, it usually is known as an “HD-15” (High Density 15), distinguishing it from connectors of like form factor, but with only 2 rows of pins. One must usually have an VGA to RCA Converter so that certain graphics cards will recognize it for your computer or TV. When device size is a spatial constraint (i.e. laptop computers), a mini-VGA port occasionally is in place of the full-sized VGA connector.
