Question
The number of pixels displayed on a screen is known
asSolution
The term display resolution is usually used to mean pixel dimensions, the maximum number of pixels in each dimension (e.g. 1920âĂâ1080), which does not tell anything about the pixel density of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not the total number of pixels.
