Video Graphics Array adaptors (VGA) are currently used because they produce high quality graphics. The VGA adaptor provides up to 256 colors and also a high resolution. There are two typical combinations of resolution and color that a VGA provides:
- 640 x 480 pixels with 16 colors
- 320 x 200 pixels with 256 colors
The resolution and colors of various display adaptors can be different from the values given above, depending on who manufactures them. The VGA, like the EGA, is quite expensive.
