The throw is 19' to a 120" screen. This is without using zoom. Will the image be bright enough to use on a perf screen? That way I could hide my speakers.

Thanks

My Panny 900 works great with a 120" 2.37 A.T. screen. My throw is about 15'. Our room is light controlled (not a cave), but we do have dark carpet and a dark painted ceiling as well. If I turn out all the lights and block 95% of the outside light my picture looks great. If your room is dark enough you should be fine with an A.T. screen. My A.T. screen is the Center Stage screen from Seymourav.com, and I love it.
