Correcting skewed or distorted image

For the best projection, project images on a flat screen
installed at 90 degrees to the floor. If necessary, tilt the
projector using the two adjustment feet on the bottom
of the projector.
1. Tilt up the projector to the appropriate angle.
2. Rotate the adjustment feet for fine adjustment.
Important:
• Don't transport the projector with its adjustment
feet extended. Otherwise the adjustment feet may
be damaged.
When fine streaks are seen on
projected images
This is due to interference with the screen surface and
is not a malfunction. Replace the screen or displace
the focus a little. (See page 12 for focus adjustment.)
When the projected image is
distorted:
When the projected image is distorted, carry out any
of the KEYSTONE, CORNERSTONE, and CURVED-
mode adjustments to correct the distortion.
When the image distorts in a trapezoid shape, use the
KEYSTONE-mode adjustment. For fine adjustment
of the image shape, use the CORNERSTONE-mode
adjustment. To adjust the image projected on a curved
surface, use the CURVED-mode adjustment.
When you press the ENTER/GEOMETRY button on
the projector or the GEOMETRY button on the remote
control, the menu switches in the order of KEYSTONE,
CORNERSTONE, CURVED, regular display, KEYSTONE...
