ok, that makes sense about the 150 being mounted up there.

I went through a long period of screen research for my last basement. With my projector, I had difficulty seeing any difference with screen material and the flat white paint. The paint gave me more options for screen size so it seem logical to go that way. Unfortunately, I don't have the time to wet-sand the wall to a baby's ass smoothness this time around, and was going for a quicker method. I still have not tried nor heard much about the "screen goo" paint that looks like a way to go.
