[. . . ] The differences between these formats are stated below. We are glad to provide any DRAPER screen in the size and projection format of your choice. We can provide any size up to and including the largest published size. If you do not find the size and format you need listed, please call or fax your requirement to us, and we will be delighted to quote. Audiovisual (or AV) format screens are intended for general use. They accommodate a variety of projector types and range from square to wide horizontal in aspect ratio. AV format screens are described in terms of height x width, and are standardly furnished without black borders, although borders are optionally available. Video format screens, on the other hand, are specifically designed for use with video projectors. Their format is strictly defined as a 3:4 rectangle, and the size is usually described in terms of a nominal diagonal. Conventional models of video format screens are standardly furnished with black borders to frame the image on all four sides, allowing for video projector overscan. Tab Tensioned electric screens are routinely furnished with black borders at the sides and bottom, although black masking at the top is optionally available. HDTV format (9 high by 16 wide) is also available for high-definition television projection, Anamorphic Video and Wide Screen format (1: 1. 85). How to Calculate a Custom Size Draper also manufactures custom size screens to meet your specification. Virtually any size within the maximum shown for a given model is available. Please call for pricing on special sizes. If you need to calculate a custom size, these formulas may be useful (D = exact diagonal; H viewing area height; W = viewing area width): 3:4 Video: H = D x. 6 W = D x. 8 D = H x 1. 667, D = W x 1. 25 9:16 HDTV: H = D x. 49 W = D x. 87146 D = H x 2. 04 D = W x 1. 1475 1:1. 85 wide screen: H = D x. 4762, W = D x. 881, D = H x 2. 1, D = W x 1. 135 PAGE 17 SETUP AND ALIGNMENT PROCEDURE PROCEDURE OVERVIEW There are several situations to consider when performing the setup procedure for the PRO895X System. The setup procedure will vary depending on the required physical and signal configuration. The simplest setup is that of a "factory configured" projector which will use the preset conditions. Factory configured means it has been aligned for ceiling/front projection and a 80" wide display at a projected distance of 96 3/8". (See pages 20 and 21. ) In this case, using the customer's signal source, only minor blanking, phase, and convergence touch up is required. If the display size is changed, to other than 80" width or the unit is to be floor-mounted, completion of the full setup procedure is required. Setup, after a hardware repair, is the other condition.
