What term describes the ratio of the brightest white to the darkest black a display system can produce?

• A. Tones
• B. Gels
• C. Background Music
• D. Contrast Ratio

Answer: (D)

Contrast ratio describes how much brighter the brightest white can be compared to the darkest black a display can show. It’s the luminance of white divided by the luminance of black, and a higher ratio means more difference between light and dark areas, which enhances detail in shadows and highlights and makes images look crisper. For example, a 1000:1 ratio means white is 1000 times brighter than black. The other terms don’t describe this property: tones relate to grayscale levels, gels are color filters used in lighting, and background music is unrelated to a display’s luminance performance.
