The standard resolution of a notebook screen refers to the physical pixels of the TFT-LCD used, which must correspond to the logical points of the graphics card output, so LCD screens often have only an optimal display resolution. And this optimal resolution is generally the maximum resolution of the LCD panel. For example, when the resolution is 1024 × 768, it means that 1024 pixels are divided in the horizontal direction of the LCD screen, and 768 pixels are divided vertically.
