42 Displaying and Adjusting the Image
Adjusting the Height of Your Image
You can adjust the height of the image using the lens shift knob and
the projector’s feet.
Using the Lens Shift Knob
If possible, set the projector flat on a table and use the lens shift knob
(instead of raising the projector’s feet) to position the image on-screen.
This delivers the best-looking picture.
You won’t need to tilt the projector upward as long as you position it
so that its lens is at least as high as the bottom of the screen, but no
higher than the middle of the screen, as shown:
Use the lens shift knob to raise or lower the image. If the knob is
recessed, press and release it to make it extend; then turn it clockwise
or counterclockwise to move the image up or down. When you’re
finished, press the knob back in.
