It's about 36 inches lower now...little below the horizontal center line of 63 inch high screen.Yeah I read your post. What's the distance b/w where your projector is now vs when it was on the ceiling? In my case I have an 87" ceiling and with 4" mount pipe and 4.5" projector height, its about 11" above the top of screen.
Another positive byproduct is I notice less sparklies from my 1.3 gain screen. Still there, but less prominent
