Important:
• The best adjustment result can be obtained when
the lens is positioned at the center of the lateral
direction at the top in the longitudinal direction
(when the projector is installed on the floor, or
at the bottom when it is installed on the ceiling).
Before performing the keystone adjustment, reset
the lens position to the default position by using
LENS SHIFT RESET (see page 33) and then move it
to the top using LENS SHIFT (see page 12).
• 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.
• When the KEYSTONE-mode adjustment is
performed, the displayed image may be distorted.
• Depending on the installation conditions of the
projector and the screen, a perfect rectangular
image and the proper aspect ratio may not be
obtained. Slight distortion can be corrected by the
CORNERSTONE-mode adjustment.
• Noise may appear on the screen during the
KEYSTONE-mode adjustment because of the type
of the video signal being projected and the setting
values of the KEYSTONE-mode adjustment. In
such cases, set the KEYSTONE-mode adjustment
values in the range where the image is displayed
without noise.
• When you carry out the KEYSTONE-mode
adjustment and the CURVED-mode adjustment
in combination, the adjustment range becomes
narrower than that in the case where you carry out
these adjustments individually. When setting the
KEYSTONE-mode adjustment value to 11 or larger,
you cannot use the CURVED-mode adjustment.
• When carrying out the KEYSTONE-mode
adjustment while the option lens is in use, you
may not be able to obtain a perfectly rectangular
image or the correct aspect ratio. Slight distortion
can be corrected by the CORNERSTONE-mode
adjustment.
Adjustment using the CORNERSTONE mode:
Use this adjustment for fine adjustment of the image
shape. For adjustment, press the ENTER/GEOMETRY
button on the projector or the GEOMETRY button on
the remote control to display the CORNERSTONE
mode and then press the
,
,
or
button.
