Screen resolution refers to the number of pixels arranged in a rectangular grid on a computer or device monitor, typically expressed as width × height (for example, 1920×1080). Higher screen resolutions provide more detail and sharper images, while lower resolutions result in less clarity and visible pixelation.
In photography and digital imaging, screen resolution is important for accurately displaying images, assessing sharpness, and previewing how photos will appear on different devices. Understanding resolution helps photographers and designers ensure their work looks its best across monitors, tablets, and other digital displays.
