contrast ratio
Screen darkness range
Contrast ratio measures the difference between the brightest and darkest values a display can produce, expressed as a ratio like 1000:1.
Higher ratios mean deeper blacks and more vivid images.
The specification matters most for viewing in dark rooms, where poor contrast makes blacks appear washed out and gray.
The TV's contrast ratio looked impressive on paper but disappointing in practice.
