From "pictures" or "pix," and "elements." The smallest part of the video screen that can be turned on or off or varied in intensity. If your monitor is in color, a pixel is three dots together, or clusters of red, green and blue. VGA has 640 pixels across by 480; Super VGA has 800 by 600 or 1024 by 768. The greater the number of pixels, the higher the resolution.
