What is Contrast Ratio
Contrast ratio is the measure of the difference between the brightest colour (white) and the darkest colour (black) that an image projector is capable of producing. Usually, a projector with low contrast ratio offers a poorer, dull, washed-out image with some parts that may be difficult to see clearly.Projectors with a low contrast ratio typically have a scale below 500:1.

They are not ideal to be used in long distances and in daylight conditions. If you are looking for a projector that offers crisp, clear and attractive images, you will find medium-contrast and high-contrast projectors to be very effective. These projectors usually have ratios that can range from 500:1 to 1200:1 and higher.
