VGA board

A VGA board is a video card for a computer that supports the VGA format. It processes the information sent to it and sends video signals to the monitor via a VGA connector. A VGA board processes the information it receives from a computer and sends it to the monitor in five separate signals. Three signals contain discrete information for the levels for red, green and blue, the primary video colors. Two more signals contain horizontal and vertical synchronization information. The color signals illuminate pixels on the monitor by mixing levels of the three to create any single color. The synchronization signals ensure the correct pixels get illuminated a the correct time. VGA offers the highest quality screen presentation of all analog formats.

Video cards, also called graphics cards or display adapters, come with a wide variety of options with prices from under $100 to several thousand dollars. The simplest version processes information and sends it to a monitor with a composite video connection on a single coaxial cable. A better video card sends analog VGA signals for a higher quality monitor presentation. As quality increases, video cards include options for digital outputs, and professional models can include inputs for video editing and animation. A VGA board would only support the VGA format
