You misread me somewhere. I never said my screen is a 120.
In post #3 of this thread, you wrote...
Our screen is an 80" diagonal.
8 posts later, in post #11 of this thread, you wrote....
My screen is a 10' diagonal.
10' = 120". Now, you're claiming you never wrote that your screen is 120" as if that is somehow different from 10'. This is weird.
The event was an opening for a local Audio FX store.
Audio FX is a rep for Stewart Filmscreen.

There are lots of folks that treat the wall for projection.
Yes, but most of those people are DIY'ers on a tight budget. I've never seen a high end dealer resort to a treated wall in a theater demo room and it seems even less likely when the dealer is a rep for Stewart. Your story isn't making a whole lot of sense.
