Your screen resolution is the number of horizontal and vertical pixels that your monitor displays. Most often, it is displayed as Width x Height (for example, 1152 x 768). The more pixels your monitor can display, the better the quality of text and images will be. Older cathode ray monitors used to maintain low resolutions (around 640 x 480), but nowadays, modern digital monitors have a higher pixel density and are constantly improving in technology. Knowing how to determine your screen resolution can be helpful, so in this article we'll show you how to do this for the most common operating systems.
