Of note, since the InFocus IN83 lacks a dynamic iris, it really is at a disadvantage to projectors that do use one. Those dynamic irises, however, are most effective in extremely dark scenes with no bright areas, and there, projectors like the Epson UB series, and the Sony VW40 and VW60 should be able to produce a blacker black. Once, however, you switch to scenes that also have more than a little extremely bright areas, dynamic irises lose their effectiveness, and on images like that, the InFocus IN83 becomes the equal of most of the other best projectors. It still can't quite catch the two best projectors without dyanmic irises, the JVC RS1x and RS2, but everything else is fair game, including the Epson and Sony 1080p competitors! For the first time in quite a while, I haven't been able to do a side by side photoshoot. My intent was to put the IN83 up against the Epson Home Cinema 1080 UB, for black level comparisons. Turns out, though, that the last upgrade to my Sony PS3, has confounded my Gefen HDMI splitter/switcher. They are sending me a component to upgrade, and when it comes - if it does the trick, I'll reshoot a couple of images suitable for determining black levels, and further confirm what I believe based on viewing the IN83, and from alternating between it, and the Epson, in my testing room. This first image is from Space Cowboys (Blu-ray) - a nice dynamic, dark scene with a small area of bright white, and also bright red. This can be challenge for a projector with a dynamic iris, as it will limit how much the iris can close down. Since the IN83 does not have a dynamic iris, its black level performance is consistent, regardless of the amount of bright areas:
