Hi I have been thinking about the best way to have a screen come down in front of my TV, when it's time to watch projector-worthy stuff, and then disappear when its back to regular TV. My first thought was to frame-mount a 100" screen and then have it "deploy" down from the ceiling by motor and gears, then tuck back up when not in use. I wanted to avoid a roll-down screen because I had always assumed that they do two bad things; one, wrinkle in the corners, thereby distorting that part of the picture, and two, swing back and forth a bit if there's any breeze in the room. I really do mean light air movement, not a howling gale. So, are these valid concerns? Is there a way to ensure no corner wrinkles on rolled-down screens? And is screen movement a problem at all? Thanks. If I can use a roll-down screen, it simplifies things immensely. Cheers, Tom.
