Screen will be 100" and I'd like to keep the screen at least 18" off of the floor. My throw distance won't really matter as I have about a 30' long space it's going in. I'm looking for any suggested mounts that will work well with a drop ceiling. Thanks!
The W1070 needs to be 3" above the top of the screen.
18" + 49" = 67" from the floor to the top of the screen.
82" - 67" = 15" from the ceiling to the top of the screen.
Center of projector lens must be 12" from the ceiling.
Almost any mount which offers an adjustable column length will allow this to work. You do have some lens shift with the W1070 which calls out about a 20% of image height shift, so it does seem like you have about 10" of total play with that image height, but I can't tell you where the high low points are... From the Projector Central review, the indication is that the lowest point would be even with the top edge of the screen - which means 15" from the ceiling. The top most position would be about 20% of the screen height which is about 9" higher, so about 6" away from the ceiling. Unfortunately, the Projector Reviews website has a review which states explicitly that the W1070 can only be about 6" above the top of a 100" diagonal image. I have not personally played with the lens shift on my projector enough to know for sure what the full range is, and the BenQ manual does NOT list the range for which the W1070 can actually handle.
Still, this range of several inches will work with many universal mounts.
I'm personally a huge fan of the Chief RPMAU mount which is expensive, but better than any other mount I've ever laid my hands on and allows you to use an extension column of your own choosing.
