Transmits three colors (red, green, and blue).The connection of various electronic devices can happen quickly like TVs, computers, CRT monitors.DVI-D Dual Link Digital Video Cable - M/Mīelow are some advantages and disadvantages of using a VGA connector:.VGB Female To F Type Coaxial Cable Connector.VGA Male to DVI-D Male with Power Cable.There are various connectors available in the market. D-sub connection type (five row configuration) or DB-15 connection type (three-row configuration).Two alternating clock pins for communicating with attached devices.The ground shield between red, green, and blue data pins.Transmits three different colors (red, green, and blue).The Features of a VGA connector are as follows: Pin 9(KEY):+5V DC output from graphic card Pin 1(Red): Red Video(75 ohm,0.75V peak to peak)ĩ. The Configuration of a VGA connector consist of 15 pins:ġ. The standard five-pin row version is DB-15. You're likely to find the D-sub version on older computers, VGA cables, and displays. The version with three hooks is D-subminiature. IBM created two versions of the VGA connector, one with five pins per row and another with three per row. The VGA cable does carry the video signal, and you must convert it to something that your monitor can understand. It does have an analog audio signal left and proper channels, but it needs conversation by a separate cable (usually through 3.5mm jacks). A device sending a digital video signal will send ones and zeros down the wire, resulting in no voltage change.Ī common misconception of VGA is that it carries audio. That is in contrast to digital video interfaces like HDMI. The 15 pin VGA connector is analog-only, which means it can only transmit varying voltages over time. That was not the first analog video interface, but they adopted it widely. IBM Developed VGA to use it with their new line of PCs called PS/2. VGA is an acronym for "Video Graphics Array." There are three rows of five pins for fifteen pins in the physical connector. The first row of pins is for red, green, and blue video data.Īfter reading this blog post, you'll understand more about how the VGA connector works and why it's essential for you. The three rows are the key to understanding what's going on with analog signals. But what are all those pins?Ī VGA connector is a 15-pin D-shaped plug with three rows of five pins. It's also an easy way to get sound from your computer speakers. The VGA connector pinout has been around for many years and is the standard analog computer video output.
