Adjusting the Projection Distance Position the projector perpendicular to the screen with all feet flat and leveled to achieve an optimal image. Move the projector forward or backward if the edges of the image are distorted. • The projector lens should be centered in the middle of the screen. If the lens center is not perpendicular to the screen, the image will be distorted, making viewing difficult. • Position the screen so that it is not in direct sunlight or room light. Light falling directly onto the screen washes out colors, making viewing difficult. Close the 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. Standard Setup (Front Projection) Place the projector at the required distance from the screen according to the desired screen size. (See the tables below.) The figures in the tables are based upon projecting an image so that it occupies the entire screen. x yz Setup & Connections When using a normal screen (4:3) In case of setting the 16:9 picture to the full horizontal width of the 4:3 screen. 4 3 : Screen area : Picture area Screen size (4:3) Diag.
