Projector contrast ratio refers to the difference in brightness between the brightest white and the darkest black that the projector can produce. A higher contrast ratio means the projector can have a broader range of brightness levels, resulting in more vivid and detailed images. Typical contrast ratios for projectors range from 1000:1 to 20000:1.
There are several ways in which contrast ratio can be measured on a projector, including
● Full On/Off: This method measures the difference in brightness between the projector's brightest white and darkest black when displaying a full white screen and a full black screen, respectively.
● ANSI: This method measures the contrast ratio by displaying a checkerboard pattern of black and white squares and measuring the difference in brightness between the white and black squares.
● Dynamic: This method measures the contrast ratio by adjusting the projector's brightness in real time to account for changes in the displayed image.
● Native: This is the projector's contrast ratio before any adjustment or enhancement.
It's important to note that different methods may result in different contrast ratio measurements, and manufacturers may use other methods to report contrast ratio.
