The smooth-running electric motor allows the SC-E100D43 to scroll up and down with its in-line switch. The scratch resistant steel white case will protect the screen when its not in use as well as blend into any decor. Once the screen is pulled down, enjoy the screen's matte white viewing surface, which diffuses projected light uniformly over the screen- creating ideal viewing from any angle. Black masking borders around the sides of the screen increase picture focus and contrast. The HDTV (widescreen) versions include a black masking border above the image for a crisp clean look. Mustang's Electric Screen is the ultimate electric projection screen.
