Problem

Solutions: VGA (Video Graphics Array): The VGA is an analog video controller. It handles color in much the same way as a TV receiver. The VGA produces a signal that can vary in small increments over a large spectrum of colors. The VGA requires an analog color monitor. VGA is a bit-mapped graphics adapter with abilities far beyond that of EGA or CGA. A VGA adapter can display up to 256 different colors simultaneously with up to 1024 X 768 resolution and sometimes greater. Because of the abilities of VGA, most VGA adapters are equipped with least 512K or more of RAM to help in displaying high-resolution graphics. Standard VGA provides a text mode with a 9 by 16 dot box for characters, and it provides its own graphics mode with 16 colors and 640 by 480 pixel resolution.
