How to calculate the resolution


The resolution (known by RTHK) is the precision of the screen image, which refers to the number of pixels that the display can display. Since the dots, lines and faces on the screen are composed of pixels, the more pixels the display can display, the finer the picture, and the more information that can be displayed in the same screen area, so the resolution is a very important performance. One of the indicators. Think of the entire image as a large board, and resolution is the number of intersections of all warp and weft.


For a screen with a resolution of 1024×768, that is, each horizontal line contains 1024 pixels, and there are 768 lines, that is, the number of scanning columns is 1024 columns, and the number of rows is 768 rows. The resolution is not only related to the display size, but also affected by factors such as the pixel pitch and video bandwidth. Among them, it has a close relationship with the refresh frequency. Strictly speaking, only when the refresh frequency is “no flicker refresh frequency”, how much resolution the display can achieve, can be called the highest resolution of this display.
