feet extended. Otherwise the adjustment feet may

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.)

distorted:
When the projected image is distorted, carry out any
of the KEYSTONE, CORNERSTONE, and CURVED-

perpendicularly to each other, projected images
become trapezoidal. If you cannot place them

You can correct the distortion vertically or horizontally
focusing on the screen center.

mode, the distortion correction is reset.
Important:
• For proper KEYSTONE-mode adjustment results,
reset the lens to the factory-adjusted position using
LENS SHIFT RESET in the INSTALLATION 1 menu
before carrying out KEYSTONE-mode adjustment.
(See page 34.)
• When the KEYSTONE-mode adjustment is carried
out, the adjustment value is indicated. Note that
this value doesn't mean a projection angle.
• When the KEYSTONE-mode adjustment takes
effect, the resolution decreases. In addition, stripes
may appear or straight lines may bend in images
with complicated patterns. They are not due to
product malfunctions.
