I was lost, but now I'm found.
I had no idea that there were so many different screens. I thought my only choices would be grey or white. Thankfully Brian at projectorscreen.com was super helpful. He spent over 45 minutes discussing my room, projector and lighting to help me decide on the best screen within my budget.
I spent a little more than I had initially intended but know that I ended up with the best quality screen for my JVC D-ILA projector!
