Video Card Pin Assignments

Every computer has either a separate video card or built in video circuitry that sends electronic signals to the monitor so information can be viewed on the screen. The actual connector that is affixed to your video card is called a DE-15 Connector. This is probably due to the fact that is has 15 female output signal pins. Therefore, this technical brief will depict the various functions of the DE-15 Video Connector.

Changing your video card is a pretty common computer upgrade particularly for avid gamers. The newest games and other online video games require powerful graphics cards to run effectively. Choosing a card with 2GB of memory or more is recommended for the best single monitor gaming experience.
