I wonder if it is possible to get a da-lite high contrast high power screen (to help with some ambient light, e.g., reflections, not 3D) with a fabric frame stitched to it. presumably, I could then nail this to the wall. do I really need a frame? the frames seem to be quite expensive, judging from the fact that a mechanic pull down screen is cheaper than a simple squared box.
I am trying to figure out how much the fabric itself costs, too. not easy to do. anyone know how much the HC HP or similar material for a 120" 16:9 screen should cost?
