Contrast ratio of a projector is the difference between the darkest blacks and the purest whites your projector is capable of displaying and the higher this ratio the more detail you get in the picture.
The 400:1 ratio you're looking for is an ANSI value and is great for presentations in offices and schools. You should know however that this might not be good enough if you intend to watch movies at home and desire that cinematic effect.
Our selection of the best projectors is narrowed down to the top rated projectors which have a contrast ratio of 400:1.
