When paired with bright HD projector (2,000+ lumens) FlexiGray Projector Screen Material provides a sharp high-definition image because its surface has little to no texture. FlexiGray is perfect for outdoor use; it is made of 100% PVC material and has a mildew resistant coating. It offers great indoor viewing results as well. As its name suggests FlexiGray is a very flexible and foldable material which makes it highly portable. FlexiGray front projection screen material works best when tension-mounted/stretched tightly and evenly in all four directions; for a flat, clear, crisp image (like a drum). If ease of installation is your priority, select an option that is rolled on a tube to avoid folds and wrinkles.*
