Extended data:

Display resolution (screen resolution) is the accuracy of screen image, which refers to how many pixels the display can display. Because the points, lines and surfaces on the screen are all composed of pixels, the more pixels a display can display, the finer the picture will be, and the more information can be displayed on the same screen area, so resolution is one of the very important performance indicators.

The whole image can be imagined as a big chessboard, and the resolution is expressed by the number of intersections of all warp and weft. When the display resolution is fixed, the smaller the display screen, the clearer the image. On the contrary, when the display screen size is fixed, the higher the display resolution, the clearer the image.
