What Screen Resolution Means and When More Pixels Help
Screen specifications often include numbers such as 1920 × 1080, 2560 × 1440, or 3840 × 2160. These numbers describe the display’s pixel resolution: the number of addressable picture elements arranged horizontally and vertically. More pixels can produce sharper text and finer image detail, but resolution alone does not tell you how large things will appear, how much workspace you will have, or whether the difference will be obvious in everyday use.
