BenQ W7000 Dynamic Iris
The W7000 uses a dynamic iris. The verdict is still out as to how good blacks will be. The engineering sample does not have black level performance rivaling that the the older W6000. The "good news" is that in conversations with BenQ, they have said that:
"We did the measurement of the latest unit of W7000 and W6000 we have, and the result shows that they are about the same."
Since these are so similar projectors (but for the 3D and a slightly more powerful lamp for the W7000), I would expect them to be essentially the same. And we plan to confirm (or deny) this as soon as we can get a full production projector, or a firmware update for our engineering sample.
If all proves well, the W7000 should turn out to be a good ultra high contrast projector. The W6000 was and we were very pleased. The W6000 was roughly the equal or better than the Panasonic PT-AE4000, but blacks weren't quite as black as the Epson Home Cinema 8700UB.
BenQ W7000 Projector 3D
The 3D is about as bright as any I've seen so far. The W7000 is right up there with the Epsons and the Panasonic. Like the others, it has right around 2000 lumens to work with, and that's pretty respectable.
In truth, the W7000 is probably the brightest of the group in its Dynamic mode. Since the dynamic mode isn't that great looking color wise - a native lamp mode, we much preferred using the calibrated mode, giving up only a few hundred lumens, and essentially seems just a tad less bright than the Epson. But not enough to worry about, especially since the W7000's color in 3D in its calibrated mode, is better than the color of any of the other projectors, at their brightest.
In other words, the BenQ is certainly fully competitive with those other bright 3D projectors, and it costs a good bit less.
Among other 3D content, I used the BenQ W7000 projector to view a bit of a college football game, Tron, some of Monster House, Ultimate Wave, Legends of Flight, and a variety of concerts, travel, and science programming in 3D. This projector was as satisfying as the Epson and Panasonic - my two favorites due to brightness combined with good color.
BenQ's glasses are a bit bulky, and run on lithium batteries. I wear glasses, and I must say, they worked rather well, with no back reflections, and a wide view. There should be plenty of 3rd party glasses that are compatible, which also includes Optoma glasses, and most others that use DLP-link.
Bottom line on 3D:
The BenQ W7000 is about as good as it gets in terms of color and brightness. It's also pretty clean in terms of ghosting, although no projector so far has been clean in 3D on all types of content. Still this is a great choice if you are really into 3D.
