What does contrast ratio signify in media?

Contrast ratio signifies the proportion of brightness between the brightest and darkest colors in media. It is a critical measurement that determines how well a display can represent different tones, from deep blacks to bright whites. A higher contrast ratio means that a display can produce a greater difference between light and dark, which enhances the perception of depth, detail, and clarity in images and video. This is particularly important in visual media, where a sharp contrast can result in more vivid colors and a more engaging viewing experience. The ability of a device to accurately reproduce these extremes in brightness directly influences the viewer's experience, affecting everything from the visibility of subtle details in dark scenes to the richness of lighter tones.
