Da-Lite > Educational Materials > Selecting The Right Screen > Front Projection Screen Surfaces Screen surface can be cleaned. Flame retardant. Mildew resistant. Number shows the degrees from the center of the axis of the screen that the projected image is brightest to the audience. Indicates Goniophotometer reflectance readings. The higher the number, the greater the light transmitted to the audience. Supported Fiberglass Matte White The most versatile screen surface and the premier choice when ambient light is controllable. It evenly distributes light over a wide viewing area while colors remain bright and life-like, with no shifts in hue. 50° 1.1 Video Spectra 1.5 Especially designed for demanding video and overhead LCD projection applications where a balance of higher gain and greater viewing angle is required. The special pearlescent surface may be cleaned with mild soap and water. 35° 1.5 Glass Beaded This surface has the ability to achieve a higher gain by reflecting more of the projected image back along the projection axis. Glass beads impregnated into the screen's surface provide additional reflectance. This attribute creates an unparalleled screen surface that reproduces vibrant life-like color at moderate viewing angles. 30° 2.5 Super Wonder-Lite Employs a scientifically designed ridged pattern, embossed into an aluminum vinyl and textile laminate. It's free from objectionable glare and hot spots, even in partially darkened rooms. Not available on all screen types since the material needs to be tensioned. 40° 1.8 High Power A technological breakthrough, combines the reflectivity of a glass beaded surface with the ability to clean the surface when required. Its smooth surface offers the highest gain of all types of screen surfaces with moderate viewing angle. 25° 2.8 Wide Power Wide Power combines the features of a higher gain screen surface of 2.2 with a wider 45 degree viewing angle. The smooth acrylic surface may be cleaned with mild soap and water. Wide Power is only available on the Deluxe Insta-Theater and the Presenter screen lines. 45° 2.2 Non-Supported Vinyl Dual Vision A unity gain flexible fabric capable of both front and rear projection. The surface is ideal for video projection where light is controllable. With its exceptionally wide viewing angle, each seat in the audience will observe a uniform, bright, sharp image with no color shift. 50° 1.0 Da-Mat A smooth, white, vinyl finish surface for precise image reproduction. Provides an exceptionally wide angle of view with little loss of resolution. It is a highly flexible unsupported vinyl fabric and may be folded or rolled. 50° 1.1 Cinema Vision A unique unsupported vinyl surface that offers a bright, uniform image with no color shift no matter at what angle you view the image. 45° 1.3 Pearlescent This surface utilizes an unsupported vinyl creating a very smooth Pearlescent coating that provides high reflectivity and brilliance without loss of image quality or resolution. 35° 2.0 Screen Borders and Drop Black masking borders are standard on all Da-Lite front projection screens except Super Wonder-Lite at no extra charge. Borders enhance the perceived brightness of an image on a screen. The human eye perceives the image to have more contrast and a sharper picture with brighter colors. Borders also allow the projected image to "bleed-off" the screen for professional appearing presentations. Drop is also available on most Da-Lite wall/ceiling and electric screens. Drop is extra fabric added to the top or bottom of the screen to adjust the screen surface to within normal viewing heights. Drop can be specified in either black or white.
