Example of Standard Setup
Setting up the Screen
Position the projector perpendicular to the screen with all feet flat and level to achieve an optimal image.
Note
•
The projector lens should be centered in the middle of 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.
lens center is not perpendicular to the screen, the image will be distorted, making viewing difficult.
•
For 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 the curtains and dim the lights when
setting up the screen in a sunny or bright room.
