VGA Research



http://en.wikipedia.org/wiki/VGA

 Software such as Xlib (a VGA graphics library for C in the early 1990s) and ColoRIX

(a 256-color graphics program), also supported tweaked 256-color modes using many

combinations of columns of 256, 320, and 360 pixels, and rows of 200, 240, 256, 400,

and 480 lines (the upper limit being 640×400 which used almost every available byte of

VGA's 256 KB video ram).

 typical 15-pin VGA pinout

 Interface VGA transfers signals of red, green and dark blue colors, and also the information

about horizontal (H-Sync) and vertical (V-Sync) synchronization.

 A video adapter (alternate terms include graphics card, display adapter, video card, video

board and almost any combination of the words in these terms) is an integrated circuit card in a

computer or, in some cases, a monitor that provides digital-to-analog conversion, video

RAM, and a video controller so that data can be sent to a computer's display. Today, almost all

displays and video adapters adhere to a common denominator de facto standard, Video

Graphics Array (VGA). VGA describes how data - essentially red, green, blue data streams - is

passed between the computer and the display. It also describes the frame refresh rates in

hertz. It also specifies the number and width of horizontal lines, which essentially amounts to

specifying the resolution of the pixels that are created. VGA supports four different resolution

settings and two related image refresh rates.

 In addition to VGA, most displays today adhere to one or more standards set by the Video

Electronics Standards Association (VESA). VESA defines how software can determine what

capabilities a display has. It also identifies resolutions setting beyond those of VGA. These

resolutions include 800 by 600, 1024 by 768, 1280 by 1024, and 1600 by 1200 pixels.
