What is better vinyl or multi-layered PVC based material for home theater screens? I don't know if it matters but it will be 120" fixed screen. The vinyl is a 1.0 gain and the multi-layered pvd is a 1.2 gain. It's a dedicated theater room with controlled lighting. I'm using a JVC model DLA-RS56 projector. The seating will be 17' and 23' away from the screen. Both have great frames wrapped in felt and the prices are very comparable.
