Screen resolution is a key specification that defines the clarity and detail of images displayed on digital screens. It refers to the number of pixels arranged horizontally and vertically—commonly expressed as width × height, such as 1920×1080. Each pixel is a tiny dot of color, and together, they form the visuals you see on your monitor, smartphone, or television. Higher screen resolutions mean more pixels, which typically result in sharper and more detailed images. For example, a 4K resolution (3840×2160) offers four times the pixel count of Full HD (1920×1080), making it ideal for large screens and high-definition content. However, resolution alone doesn’t determine image quality—factors like pixel density (PPI), screen size, and display technology (LCD, OLED, etc.) also play important roles.
