Screens. You may project the VPM500 directly on to a flat white wall. If you do, the wall should be pure white, not offwhite, eggshell or other shades. If you are repainting, look for "ceiling white': "ultra-white.; "decorator's white" or consult your paint store for a totally flat latex containing no tints whatsoever. If you choose wall projection, you should mask out a 2-inch area around the picture to avoid disturbing effects in the overscan area. (See fig. 1.) We recommend a commercial screen, however, because their special surfaces reflect more light. Minimum recommended screen size is a 6-foot diagonal (43.2" x 57.6"). The largest size projection surface we recommend is 12' x 16'. Projection screens are available from camera shops, photographic supply houses, audio-visual dealers, or from your Harman Kardon dealer. They come in two general types and three different mounting configurations. Beaded or "pin head" screens provide a slight focusing effect which looks good with floorstanding VPM500's. Metallic-coated screens yield a good result with ceiling mounted projectors. The screen may be wall-mounted, ceiling mounted or on a tripod. We don't recommend that latter, since screen alignment is very critical and a moveable screen can get bumped very easily. The cost of a screen is almost always directly proportional to its ability to disperse a bright image at a wide angle. The more expensive a screen, the wider the angle of viewing, allowing more people to sit side-by-side and still see a bright picture. (See fig. 2.) The maximum angle you require will be determined by your room layout: If the room is long and narrow, you may not need a screen with extreme wide angle capabilities. If the screen you purchase is larger on one dimension than the VPM500's projected image, you should mask the edge with black paper, cloth or non-reflective tape to give crisp, exact definition to the picture's boundaries. Speaker placement. At this time, make sure that the speakers you have chosen for use with the VPM500 will fit on each side of the screen without creating shadows. 2" min. Figure 1 Recommended picture frame to avoid disturbing effects in overscan area Screen-to-VPM500 distances. Other projection TV's allow only a few fixed screen sizes. One of the unique advantages of the VPM500 is its ability to offer an infinitely variable number of screen sizes between a 4-foot and 15-foot diagonal measurement, allowing you more flexibility in where the VPM500 projector can be placed on the floor. Some of the possibilities and relationships between screen size and projector distance are shown in the following chart: SCREEN SIZE Diagonal Measurement FT. INCHES Width & Height INCHES 6 72 7 84 10 120 12 144 15 180 20 240 57.6 x 42.2 67.2 x 50.4 96 x 72 115.2 x 86.4 144 x 108 192 x 144 * The VPM500 is precisely focused and aligned at the factory for installation on the floor or ceiling, with a flat screen for a 7-foot image and 94-inch projector-toscreen to be 12.2 inches above the floor (when the VPM500 is floor-mounted), or requires the top of the screen to be 12.2 inches below the ceiling (when the VPM500 is ceiling mounted). Large variations from these screen positions will require re-alignment by a qualified technician. PROJECTOR DISTANCE NOTES INCHES 80 94 135 rk* 163 205 275 " The VPM500 can be precisely focused and aligned for this screen size and screento-projector distance (along with many others) by a qualified technician. The customer should not attempt to focus or align the VPM500 to this specification without a technician.
