Installation 3-4 Vidikron Vision Model 100 Owner’s Operating Manual Screen Type and SizeFront Screen Installations: In front screen installations the projector and audience are positioned in front of the screen, which can be flat or curved; see Figure 3-1. Flat screens are recommended with this projector. They offer a gain of about 1 with a viewing angle just less than 180°. This type of screen reflects incident light equally in all directions so the audience can see the display from various angles. Curved screens have a gain greater than 1 with a viewing angle much less than 180 degrees. This type of screen does not reflect incident light equally in all directions; instead, it is concentrated in a viewing cone. The audience sitting within the viewing cone area sees a brighter image than those sitting just outside this area. Vidikron generally does not recommend use of curved screens due to excessive brightness and uncorrectable geometrical distortion. Figure 3-1. Flat vs. Curved Screens Rear screen installations: There are two basic types of rear screens: diffused and optical. A diffusion screen has a surface that spreads the light striking it. Purely diffused screens have a gain of less than 1. The main advantage of the diffused screen is its wide viewing angle, similar to that of a flat screen for front screen projection. This type of screen is suitable when a wide viewing angle is required but there is low ambient room lighting. Optical screens take light from the projector and redirect it to increase the light intensity at the front of the screen. This reduces it in other areas. A viewing cone similar to that of a curved, front-screen installation is created. This type of screen is better suited for brightly lit rooms where the audience is situated within the viewing cone. ➤
Installation Vidikron Vision Model 100 Owner’s Operating Manual 3-5 Screen Size: Choose a screen size that is appropriate for your lens and application. The size of the room and viewing distance are the defining factors; a rule of thumb is that the primary viewing distance be 1.5 times the screen width. To fill a screen with an image, the aspect ratio of the screen should be equal to the aspect ratio of the image (expressed as the ratio of its width to its height). Standard video from a VCR has a 4:3 or 1.33:1 aspect ratio. For example, to display a VCR output with a 4:3 aspect ratio onto a 10-foot (3.05-meter) high screen, the width of the screen must be at least 13.3 feet (4 meters). Ambient LightIn general, minimize or eliminate light sources directed at the screen. Contrast ratio in your images will be noticeably reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image. Images may then appear washed out and less vibrant. Other ConsiderationsOther considerations and tips that can help improve your installation: Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry, which may affect performance. Keep the projector away from devices that radiate electromagnetic energy such as motors and transformers. Common sources of these include slide projectors, speakers, power amplifiers and elevators. Throw DistanceThrow distance is the distance measured from the front of the projector to the screen. This is an important calculation in any projector installation as it determines whether or not you have enough room to install your projector with a desired screen size and if your image will be the right size for your screen. You can quickly estimate the throw distance by taking the width of the screen and multiplying it by the lens throw ratio; see Figure 3-2. The result of this calculation tells you roughly how far back the projector should be positioned from the screen in order to project a focused image large enough to fill the screen. Figure 3-2. Estimating Throw Distance Estimating Throw Distance Throw Distance (TD) = Screen Width (w) x Lens Throw Ratio Screen width (w) TD
Installation 3-6 Vidikron Vision Model 100 Owner’s Operating Manual Table 3-3 lists the available lens options for the Vision 100 and their associated throw ratios. Vertical and Horizontal Position Proper placement of the projector relative to the screen will yield a rectangular, perfectly-centered image that completely fills the screen. Ideally, the projector should be positioned perpendicular to the screen and in such a way that the lens center and screen center are aligned with each other, as shown in Figure 3-3. Figure 3-3.

Installation Vidikron Vision Model 100 Owner’s Operating Manual 3-7 Vertical and Horizontal Lens Shift If it is not possible to align the projector and screen as shown in Figure 3-3, you can use the lens shift controls to center the image on the screen. Lens shift is generally expressed as a percentage of the screen height or width, as shown in Figure 3-4 and Figure 3-5. Figure 3-4. Vertical Lens Shift Figure 3-5. Horizontal Lens Shift These are general examples of lens shift. Lenses vary in their shift capabilities. No particular lenses were used in these examples.Note Base plate to center of lens Approx. 5-6 (depends on the amount of lens shift) 50% Height Lens Shift (0.5 x H)100% Height Lens Shift (1.0 x H)150% Height Lens Shift (1.5 x H)Screen Center0% 0%Screen Center 100% Width Lens Shift (1.0 x W) 50% Width Lens Shift (0.5 x W) 150% Width Lens Shift (1.5 x W) Screen Width (W)
Installation 3-8 Vidikron Vision Model 100 Owner’s Operating Manual Generally, a higher lens throw ratio means greater lens shift capability. Table 3-4 lists the lens shift limits for each available Vision 100 lens, as percentages and absolute measurements with a 100 x 56 inch (1.78:1) screen. Adjusting the Projection Angle If the Vision 100 is ceiling-mounted and the screen is significantly lower than the projector, you can also tilt the projector at a slight angle by adjusting the ceiling mount. If you do this, you may need to shift the image using the on-screen display (OSD) controls, to compensate. For detailed instructions, refer to Using the On-Screen Menus on page 4-2. Table 3-4.

Installation Vidikron Vision Model 100 Owner’s Operating Manual 3-9 MountingThere are several methods for mounting the projector. Depending on your chosen installation, one method may be more suitable than another. Floor Mounting: In typical front and rear screen installations the projector can be mounted to a secure and level surface, such as a table or cart. Carts are useful when moving a projector during a presentation or from site to site. If possible, lock the wheels when it’s in position to prevent it from being moved during a presentation. Ceiling Mounting: The projector can also be inverted and suspended from the ceiling using a specially designed ceiling mount fixture. This type of mounting is recommended for fixed installations and for those that want the projector out of sight or have a limited space for projector and audience. Folded OpticsIn rear screen applications where space behind the projector is limited, a mirror may be used to fold the optical path, as shown in Figure 3-6. The position of the projector and mirror must be accurately set. If you are considering this type of installation, contact your dealer for assistance. Figure 3-6. Folded Optics Use only the Vidikron-approved ceiling mount kit designed for your projector. Note
