I have a related question, if I may. I was thinking about purchasing this projector when I looked at NEC's distance calculator and noticed the large offset. I would like to mount the projector to an 86" basement ceiling, but that would put the bottom of an 80"x45" screen less than two feet from the floor. Reducing the screen size doesn't help much. So my question is, how does the Keystone correction affect PQ? Some have suggested I avoid this projector partly because of the offset. I suppose I could always jack up the house . . .
