Adjusting the Image Position Using Lens Shift
If you cannot install the projector directly in front of the screen, you can adjust the position of the
projected image using the lens shift feature.
Follow these guidelines when using lens shift to adjust your images:
• When adjusting the image height, position the image lower than where you want it to be and then
move it up using the vertical lens shift dial. This helps prevent the image from moving down after
adjustment.
• Keep the vertical and horizontal lens shift dials in their center positions for the clearest picture.
Note: Wait 30 minutes after turning on the projector before setting the focus, zoom, and lens shift for
maximum accuracy.
1. Turn on the projector and display an image.
