A height adjustable bottom black border is also added to raise the screen further from the ground, to normal viewing height.

The HamiltonBuhl Matte White projector screen fabric evenly distributes light over a wide 110 viewing area, while colors remain bright and life-like, with no shifts in hue or contrast. With a 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.
