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.
Display resolution refers to the pixels displayed on screen.
Display resolutions used by various Sega consoles and arcade systems:
256×192 - 49,152 pixels
256×224 - 57,344 pixels
256×240 - 61,440 pixels
320×224 - 71,680 pixels
320×240 - 76,800 pixels
320×448 - 143,360 pixels
320×480 - 153,600 pixels
