Projector Review's Sharp 17000 review reaches a wrong conclusion because of Art's bias towards gray screens. For 3D projectors, grey screens are a marriage made in hell. Art admits as much, yet still publishes the review!
"The 100" high contrast gray in my theater right now, really has been a marginal match up for the Sharp when in 3D. When I was doing the photo shoot, and other viewing down in the testing room, I was filling the 106" Carada Briliant White. That looked a bit better.
Not being a fan of the really high gain screens - 2.0 gain or higher, I don't have one around, but I can see where they just might be worth considering in some situations.
I often recommend high contrast gray screens lowering black levels, but since the Sharp's black levels are already pretty impressive, the higher gain will be more important for most.
Those real high gain screens have a narrow viewing cone, that is, you want to be sitting between the edges of the screen, close to the center. Even in the center with a high gain screen you will normally notice some dimming in the corners, but mostly on nice bright scenes, maybe a blue sky, or clouds. Those screens should also be good at dealing with some side ambient light, and/or allow you a brighter image or larger screen.
For most people I expect pairing with something between a 1.3 and 2+ gain, will make the most sense."
Technically speaking no professional reviewer has any business reviewing a 3D projector with a gray screen. (gray screens were a band-aid answer for inferior LCD black levels. Why anyone still uses them is questionable).
To read Art's grudgingly, self-admitted poor setup of a fine 3D projector, then whine being forced to change to something which improve the picture quality is beyond belief.
Now he plans to get a hugely expensive, polarized high-gain silver screen, when the DLP light is not polarized to begin with. (Then he will whine about the sub-standard 2D picture quality).
A reasonable price, high-gain white screen would seem just the "hot ticket" but is ignored. Go figure!
