When fi ne 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 15 or 20 for focus adjustment.)
When projected images are distorted to a trapezoid
When the screen and the projector are not placed perpendicularly to each other, projected images become
trapezoidal. If you cannot make the projector and the screen perpendicular to each other by mechanical adjustments,
adjust keystone.
To adjust keystone:
Press the KEYSTONE button on the projector or the remote
control to display KEYSTONE, and adjust the image by
pressing the or button (or VOLUME + or - button on the
remote control).
Important:
• For proper keystone adjustment results, reset the lens to the factory-adjusted position using LENS SHIFT RESET
in the INSTALLATION menu before carrying out keystone adjustment. (See page 24.)
• When the keystone adjustment is carried out, the adjustment value is indicated. Note that this value doesn't mean
a projection angle.
• The allowable range of the adjustment value in the keystone adjustment varies depending on the installation
conditions.
• When the keystone 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 adjustment is carried out, the image may not be displayed correctly because of the type of
input signal.
• When the keystone 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.
• Noise may appear on the screen during the keystone adjustment because of the type of the video signal being
projected and the setting values of the keystone adjustment. In such cases, set the keystone adjustment values in
the range where the image is displayed without noise.
• In the keystone adjustment with the option lens, the proper aspect ratio may not be obtained.
