I have a white dry wall that I would like to use to watch 3d movies. I calculated the screen size and it should project maximum of 150 inches on this wall (If i choose a short throw PJ). I'm still researching on getting the BenQ w1070, Benq w1085, or Epson 3000. But in general can any projector display 3d on a regular white dry wall? Eventually I will get a screen, but that would be another question in the future.
