Screen resolution refers to the number of distinct pixels displayed on a screen, typically measured in width × height (e.g., 1920×1080). It determines the clarity and detail of images, text, and video on digital displays such as monitors, smartphones, and televisions. Higher resolutions mean more pixels, resulting in sharper visuals and more workspace for multitasking. Common resolutions include HD (1280×720), Full HD (1920×1080), 4K (3840×2160), and beyond. However, resolution alone doesn't guarantee image quality—factors like screen size, pixel density (PPI), and display technology also play crucial roles in the viewing experience.
