I have a Marantz VP8600, which is a great quality 720p projector. It is all that I have ever had, and is all that I know. From what I understand, there are projectors out there that are light cannons. If you were to properly calibrate both projectors, to the correct contrast and brightness using the same setup disc, in theory, would the "brighter" projector perform any differently? (I am strictly talking about its ability to throw a bright image)
