BTW, Bill, that PX 1 PRO Projector is NOW available from AmazonUS for $1799 if you apply their $100 off coupon. VERY SUSPICIOUS and reviews of their other projectors are extremely mixed citing POOR customer service!

From a 3-D standpoint Hisense mentions "polarized" 3-D. I'm guessing that's an error and instead will use standard DLP 3-D shutterglasses. Reason being is a projector doing polarized 3-D would require a special silver screen specifically designed for use with polarized 3-D. And that special screen could cost as much as the projector.
