The resolution is the size of an image. Usually, resolution is denoted by width x height (in pixels). For example, a Mega Drive screenshot has a resolution of 320x224 pixels in NTSC regions, however, the resolution in PAL regions is 320×240. It is noted that not many games take advantage of the extra resolution, leading to borders around the top and bottom of the screen.
