A setting that determines how much information is displayed on the computer screen, measured in horizontal and vertical pixels. When the screen resolution is low (for example, 640 x 480), fewer pixels are displayed on the screen, but the size is relatively large. When the screen resolution is high (for example, 1600 x 1200), more pixels are displayed on the screen, but the size is relatively small.
The display resolution is the number of pixels displayed on the screen. The resolution of 160× 128 means that there are 160 pixels in the horizontal direction and 128 pixels in the vertical direction. With the same screen size, the higher the resolution, the finer the display effect will be.
