Setting up the Screen Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image. Notes • The projector lens should be perpendicular (square-on) to the screen. If the horizontal line passing through the lens center is not perpendicular to the screen, the image will be distorted, making viewing difficult. • For an optimal image, position the screen so that it is not in direct sunlight or room light. Light falling directly on the screen washes out the colors, making viewing difficult. Close curtains and dim the lights when setting up the screen in a sunny or bright room. • A polarizing screen cannot be used with this projector.
