By the way, Kraine reports minimal brightness is 1216 lumens, which is too high, I believe.
So, perhaps W1070 can benefit from ND (2 or even 4) filter for 2D movies? Nayr what do you think?
Yes, I think it would benefit. I tried some of the darker scenes in "Cowboys and Aliens", and the black levels were bright enough to be distracting. That said, it's better than the Acer I had and the few other budget projectors I've seen.
