Oops, somehow I incorrectly reported the screen at 180, it's actually 150 diagonal 16:9 screen. This may open it up to a few more options.
From some of my research, in addition to the BenQ W1080ST (which I think at best would produce 12FL) I also found a couple of others:
- BenQ W1500: has some vertical lens shift. From the throw calculators, this looks like it could be an option at 11' 8" - 14' 4" range (15-18FL).
- ViewSonic PJD7820HD: appears to be happy around the 12' 4" to 14' range.
I'm not sure of the performance of any of these 3 projectors, but maybe someone has some experience.
