The Fixed Frame Screen is one the best choices for Home Theater, thanks to its high performance matte white fabric and it''s outstanding optical performance. The fixed frame screen also complements any situation where a permanent wall-mounted solution is preferred - such as an auditorium, conference room, or in a house of worship. Fixed Frame Projector screens generally require more assembly than other screen types, however they are more easily wall-mounted(simply hanging like a picture frame on the included brackets), requiring less installation and no electrical connectivity. Matte White - The most versatile screen fabric surface and the premier choice when ambient light is controllable. The Matte White projector screen fabric evenly distributes light over a wide viewing area, while colors remain bright and life-like, with no shifts in hue or contrast. The 120° viewing angle allows for a very wide audience seating arrangement. With an even Gain of 1.0, this projector screen fabric allows for no loss of brightness from the projection source, as long as ambient light is controlled. A black backing to the fabric is also added to impede any light penetration from behind the projected surface.The matte white screen surface can be easily and safely cleaned with mild soap and water. Do not use any other stronger chemical cleaners, as this may negatively affect the projection surface. The fabric surface is also flame retardant and mildew resistant.
