As you probably already know, the contrast specifications on projectors are not reliable guides to the real contrast you experience when viewing the image on the screen. A primary reason for this is that when the projector has an automatic iris, "full on/full off" contrast measurements yields different results when the iris is on and when it is off. It is not always clear from the specs whether a projector has an auto iris, or if it does, whether the contrast rating was done with that feature activated or not. If the auto iris is off during the contrast reading, it will inevitably yield a lower number, normally referred to as native contrast.more
