Contrast ratio of a projector is essentially the difference between the darkest blacks and the brightest whites your projector can display. So, if this ratio is higher you get a whole lot more detail in the picture.
However, the thing about contrast ratios is that even the difference between 400:1 and 4000:1 is hardly noticeable in bright rooms. Ambient light generally washes away the effect of contrast, so high contrast ratios are generally recommended for home cinema where the setup is in a dark room and detailed viewing is desired
Contrast ratios of projectors are measured using two standards: Full on/Full off and ANSI and the one can't be compared with the other.
ANSI contrast ratio is the more recommended of the two since it represents a more operative value. It is calculated using a checkerboard of 8 black and 8 white rectangles. The contrast is the average light output of all the white checks against the black ones. ANSI contrast ratio makes way for some ambient light that would be present in a realistic setting. of the two averages obtained. The Full on/ Full off measurement is a more idealistic ratio which is not very applicable to our rooms. It yields very high values like 400000:1 and could be misleading.
The 4000:1 ratio you're looking for is an ANSI value and is great for presentations in offices and schools too.
Our selection of the best projectors is narrowed down to the top rated projectors which have a contrast ratio of 4000:1.
This list of the best projector with contrast ratio 4000:1 is also applicable for the following topics:
