I'm about to make a 108" (9') wide screen for my HS20 projector.
Could someone help with 2 questions:
1. What height should the screen be?
16:9 = 108" x 60.75"
or
1.85:1 = 108" x 58.38"
2. What gain should the fabric be? (Harkness Hall do something called 'Perlux 140', with gain=1.4, is this suitable?)
