Display resolution
The display resolution of a digital television or computer display typically refers to the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by all different factors in cathode ray tube (CRT) and flat panel or projection displays using fixed picture-element (pixel) arrays. One use of the term “display resolution” applies to fixed-pixel-array displays such as plasma display panels (PDPs), liquid crystal displays (LCDs), digital light processing (DLP) projectors, or similar technologies, and is simply the physical number of columns and rows of pixels creating the display (e.g., 1280×1024). 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. Note that the use of the word resolution here is misleading.
