Display resolution

The display resolution of a computer display typically refers to the number of distinct pixels in each dimension that can be displayed &is simply the physical number of columns and rows of pixels creating the display (e.g., 12806x768). It can be an ambiguous term especially as the displayed resolution is controlled by all different factors in cathode ray tube (CRT) & flat panel or projection displays using fixed picture-element (pixel) arrays.
A consequence of having a fixed grid display is that for multiformat video inputs all displays need a "scaling-engine" (a digital video processor that includes a memory array) to match the incoming picture format to the display.
Computers have higher resolutions:LCD monitors have only one native display resolution - the highest available on that particular monitor. When users select a lower resolution, the lower resolution is reported to the statistics gathering website. Nevertheless, the actual number of pixels in front of the user has not changed. Instead, interruption in the monitor causes the picture to become fuzzy as it attempts to display an image of the wrong resolution by scaling it.
