What is the term for the property of a display system that refers to the ratio of the brightest shade to the darkest shade?

The correct term for the property of a display system that refers to the ratio of the brightest shade to the darkest shade is known as the contrast ratio. This ratio is crucial in determining how well a display can represent different levels of brightness and detail, thereby affecting the overall quality of the image produced. A higher contrast ratio indicates a wider range of brightness levels, allowing for more vivid images with better differentiation between lights and darks. This is particularly important in visual media, where clarity and detail can significantly impact the viewer's experience.

Other terms in the choices, such as resolution, deal with the number of pixels in an image and how detailed it appears, while color depth refers to the number of bits used to represent the color of a single pixel, influencing the range of colors displayed. Luminance, on the other hand, measures the intensity of light emitted or reflected from a surface but does not specifically define the difference between the brightest and darkest shades in the way contrast ratio does.
