Screen resolution refers to the number of pixels displayed on a screen. It is typically measured in pixels per inch (PPI) or dots per inch (DPI). The higher the resolution, the sharper and more detailed the image will appear.
There are several reasons why you might want to check your screen resolution. For example, you may want to make sure that your screen is displaying the highest possible quality image. You may also need to know your screen resolution in order to troubleshoot problems with your display.
