page 92 Reference Guide SCREEN REQUIREMENTS Fitting the image to the screen It is important that your screen is of sufficient height and width to display images at all the aspect ratios you are planning to use. Use the conversion chart to check that you are able to display the full image on your screen. If you have insufficient height or width, you will have to reduce the overall image size in order to display the full image on your screen. 14:3 = 1.33:1 W = H x 1.33, H = W x 0.75 216:10 = 1.6:1 (native aspect ratio for WUXGA projectors) W = H x 1.6, H = W x 0.625 31.66:1 (Vista) W = H x 1.66, H = W x 0.6 416:9 = 1.78:1 (native aspect ratio for 1080p projectors) W = H x 1.78, H = W x 0.56 51.85:1 (Flat) W = H x 1.85, H = W x 0.54 62.35:1 (Scope) W = H x 2.35, H = W x 0.426 Notes Screen width 1234 567 89 10 Screen height 1 2 3 4 5 67 8 9 10 123456 Digital Projection HIGHlite 740 Series Rev I Februar y 2015
page 93 Reference Guide SCREEN REQUIREMENTS Positioning the screen and projector For optimum viewing, the screen should be a flat surface perpendicular to the floor. The bottom of the screen should be 1.2 m (4 ft) above the floor and the front row of the audience should not have to look up more than 30° to see the top of the screen. The distance between the front row of the audience and the screen should be at least twice the screen height and the distance between the back row and the screen should be a maximum of eight times the screen height. The screen viewing area should be within a 60° range from the face of the screen. Notes The projector should be installed as close to the power outlet as possible. The power connection should be easily accessible, so that it can be disconnected in an emergency. Ensure that there is at least 30 cm (12 in.) of space between the ventilation outlets and any wall, and 10 cm (4 in.) on all other sides. Do not install the projector close to anything that might be affected by its operational heat, for instance, polystyrene ceiling tiles, curtains etc. The image can be flipped for rear projection (see Setup menu in the Operating Guide ) and displayed without the need for extra mirrors or equipment. However, you must ensure that there is sufficient distance behind the screen for the projector to be correctly located. Rear installation is generally more complicated and advice should be sought from your local dealer before attempting it. Digital Projection HIGHlite 740 Series Rev I Februar y 2015
page 94 Reference Guide POSITIONING THE IMAGE Positioning The Image The normal position for the projector is at the centre of the screen. Ho\ wever, you can set the projector above or below the centre, or to one side, and adjust the image using the Lens shift feature (known as rising and falling front) to maintain a geometrically correct image. Notes For more information on shifting the lens, see Lens menu in the Operating Guide . Whenever possible, position the projector so that the lens is centered for the highest quality image.

page 95 Reference Guide POSITIONING THE IMAGE Any single adjustment outside the ranges specified on the following page may result in an unacceptable level of distortion, particularly at the corners of the image, due to the image passing through the periphery of \ the lens optics. If the lens is to be shifted in two directions combined, the maximum ran\ ge without distortion will be somewhat less, as can be seen in the illustrations below. Notes For more information on shifting the lens, see Lens menu in the Operating Guide . Full horizontal or vertical shift Combined shift is reduced Digital Projection HIGHlite 740 Series Rev I Februar y 2015
page 96 Reference Guide POSITIONING THE IMAGE Maximum offset range The maximum offset range available with no distortion or vignetting is dependent on wh\ ich lens is used. Shifting the lens beyond its undistorted limits may be physically possible, however you may experienc\ e some vignetting or distortion.

page 97 Reference Guide ASPECT RATIOS EXPLAINED Aspect Ratios Explained The appearance of a projected image on the screen depends on a combinati\ on of the following: • The DMD™ resolution: • 1080p with a 1920 x 1080 resolution, corresponding to an aspect ratio of 16:9\ • WUXGA with a 1920 x 1200 resolution, corresponding to an aspect ratio of 16:1\ 0 • The aspect ratio of the input signal: 4:3, 16:9 or 16:10 • The value of the Aspect Ratio setting of the projector: • Source - show the image with its original aspect ratio, not using the whole sc\ reen if the DMD™ aspect ratio does not match. • Fill Display - fill the screen but force the DMD™ aspect ratio on the image. • Fill & Crop - fill the screen without changing the original aspect ratio but cropping the image to fit the DMD™ aspect ratio. • Anamorphic - force a 16:9 ratio on the source. You need this setting to resolve 16:9 images packed into a 4:3 frame, oth\ erwise it distorts the image. • TheaterScope is a special setting used in combination with an anamorphic lens, an op\ tional accessory. It removes letterboxing from a 2.35:1 source packed into a 16:9 frame. Notes Digital Projection HIGHlite 740 Series Rev I Februar y 2015
