The W1070 is very bright. I mean really bright, especially when comparing to other projectors post calibration. That shouldn't be too shocking, this is primarily a "family room" projector. It's not the brightest around, as there are plenty of home entertainment projectors around it's price. Still there are only a couple of projectors that can muster up more than a few hundred extra lumens. Even when you consider other light canons like the Panassonic PT-AR100U ($1199), and the Epson Home Cinema 3020 ($1599), which are brighter, that's primarily in "brightest mode".

3D brightness is discussed in the 3D section below. If anything, that's where you really need lots of brightness.

BenQ W1070 Calibrated: User 1 "best" mode = 1711 lumens

That is rather exceptional brightness. Keep in mind Brilliant Color is engaged, so technically, you can have a better picture with BC off, but with essentially the same color balance.

This is one of the sets of images I shot with the projector slightly out of focus - my apologies.

Not a lot of zoom range, but it is 1.3:1, which is a bit more range than the 1.2:1 zooms that are so popular on low cost DLP projectors. Thus, we wouldn't expect a big drop, and voila' the drop from closest position (wide angle) to furthest placement from the screen (telephoto on the lens). All told that is a drop of less than 15%. To put that in perspective, switching from full power to eco (see below) is a much greater drop in brightness.
