"It is also common to market only the dynamic contrast ratio capability of a display (when it is better than its static contrast ratio), which should not be directly compared to the static contrast ratio. A plasma display with a static 5000:1 contrast ratio will show superior contrast to an LCD display with 5000:1 dynamic and 1000:1 static contrast ratio when the input signal contains full range of brightnesses from 0 to 100% simultaneously. However they will be on par when input signal ranges only from 0 to 20% brightness."
