The 43 x 57" Manual Projection Screen from Pyle-Home is a reasonably-priced screen that is suitable for home or office use. When you don't need or want a motorized system, this screen will meet all your demands with its simplicity of design.
The screen is activated by use of a handy pull tab - deploying and retracting with ease. The matte white surface is mildew-resistant and fire-retardant. It also generates a bright picture with its Gain of 1.1 that produces a clear, sharp image when used where your ambient light can be controlled. The screen is designed with standard black masking borders that both absorb excess ambient light and also help to keep your audience's eyes on the screen.
The viewing angle is a respectable 120° making it very useful for a classroom or learning lab setting where your audience may be of considerable size. The image is evenly distributed over the entire surface with no hot spots and no color shift. For a screen with an easily cleaned surface and that doesn't require extensive installation, this one may be the answer to your audio-visual problems.
