Adjustment of the Projection Screen
Operations include the adjustment of the image position that is projected to the screen and the adjustment of the focus as well as
the input selection and the selection of the aspect ratio.
Perform these operations with the power of the connected equipment switched on and the video signal input to the projector.
6 Projection Screen Position Adjustment
1 Adjust the projection image to the screen
(1) If the image is shifted to the left or right, move the main unit horizontally. (Align the center of the screen and the center of
the lens of the main unit.)
(2) If the image is shifted vertically, move the image up or down with the adjuster.
(3) A projection image such as that illustrated in the diagram is the result of the projector not being perpendicular to the
screen. Set the projector so that it is pointing straight toward the screen.
(4) If the image shows keystone distortion, adjust using menu operations.
