Hi

VGA (Video Graphics Array) is a basic standard for color resolution in computer monitors that, today, represents the lowest common denominator for compatibility. For example, when a computer boots into the Microsoft™ Windows™ operating system, the opening splash screen or Windows logo is presented in VGA mode using a palette of 32 colors and a resolution of 640 x 480. Once the system is fully loaded, the video card’s device driver takes over at a higher resolution.

In the early days of computers, monitors were originally monochrome or two-color. This was followed by IBM’s Color Graphics Adapter (CGA) in 1981 that boasted a 4-bit palette of 8 colors and a maximum resolution of 640 x 280. The adapter was standard in the new IBM personal computer line, known as the IBM PC.

Thanks
