Pixels And Resolution The picture element (or pixel) is the very smallest point that can be controlled on a CRT. For monochrome displays, a pixel can simply be turned on or off. Fora color display, a pixel could assume any of a number of different colors. Pixels are combined in the form of an array (rows and columns. The size of the pixel array defines the display’s resolution. Thus, resolution is the total number of pixels in width by the total number of pixels in height. For example, atypical EGA resolution is 640 pixels wide by 350 pixels high (a total of 224,000 pixels, and atypical VGA resolution is 640 pixels wide by 480 pixels high (a
total of 307,200 pixels. Typical Super VGA (SVGA) resolution is 800 pixels wide by 600 pixels high. Resolution is important for computer monitors because higher resolutions allow finer image detail.
