We have completed the construction of our contrast testing facility, and I will be posting an article focused on contrast specifications in the next couple of days.
Meanwhile, we have received two new 1080p projectors, and reviews of both of them are underway. These are the Infocus Play Big IN83, and the Viewsonic Pro8100. Right behind them is the Optoma HD65.more

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
