The Elite Screens Spectrum 84" Electric Projection Screen (16:9 Aspect Ratio) is another great choice for home or commercial use. The Spectrum comes fully assembled and is ready for immediate installation giving it a distinct advantage over other comparably priced screens in its category which need complicated construction.
The motor is quiet with a very quiet up/down function that can be controlled by the included IR remote. The 12V trigger (also included) gives you full synchronization between screen and projector - a unique feature among motorized screens. The screen finish is Elite's exclusive MaxWhite that provides a bright, crisp and clear image. The screen generates a 160deg. viewing angle making it viewable from just about anywhere in the room. In addition, the surface is easy to maintain and cleans easily.
MaxWhite Screen Material is the most versatile screen surface for front projection presentations. This material provides the widest possible viewer angles with perfect diffusion uniformity while giving precise definition, image color reproduction and black & white contrast. Screen Surface has black-backing to avoid light penetration and can be cleaned safely with mild soap and water. Woven screen material is a, multi-layer, cross array coated with a matte white reflective compound.
