NOTE:
•In terms of the optical characteristics of this projector, in addition to keystone distortion (page 102), there may be occurrences
of slight pincushion type or barrel type distortion.
To adjust the projected image with the screen, first perform Steps 9 to 11 on pages 35 to 36 (Adjustment of the projection
distance 
→ Height adjustment of the projected image → Focus adjustment), then align the 4 corners of the projected image
with the 4 corners of the screen. Following this, if the pincushion type or the barrel type distortion is conspicuous, please
perform 
 Adjusting Pincushion or Barrel Distortion (Pincushion) after you select a source you want to project.
•If the keystone distortion is not improved after pressing the FOCUS +/–  buttons and adjusting the focus, or the aspect ratio
does not agree, make sure the screen or projector are not tilted.
[Symptom1]
In the case of keystone distortion (as illustrated), either the screen is directed
slightly upward or the projector is directed slightly upward.
[Action]
Tilt the top end of the screen to the front or rotate the front feet of the projector
to correct keystone distortion.
Up
Down
[Symptom2]
In the case of keystone distortion (as illustrated), either the screen is directed
slightly downward or the projector is directed slightly downward.
[Action]
Tilt the bottom end of the screen to the front or rotate the rear feet (screen side) of
the projector to correct keystone distortion.

[Symptom 3]
As illustrated in the diagram to the right, when the left edge of the image is wid-
ened vertically, either the projector is not placed straight in front of the screen or
the projector is directed slightly to the left.
Conversely, when the right edge of the image is widened vertically, either the
projector is not placed straight in front of the screen or the projector is directed
slightly to the right.
[Action]
Place the projector straight in front of the screen.

Press the Auto Adjust button to optimize an RGB image automatically.
[Poor picture]
[Normal picture]
Press the Auto Adjust button to fine-tune the computer image or to remove any vertical banding that might appear and
to reduce video noise, dot interference or cross talk (this is evident when part of your image appears to be shimmer-
ing). This function adjusts the clock frequencies that eliminate the horizontal banding in the image. This function also
adjusts the clock phase to reduce video noise, dot interference or cross talk.
This adjustment may be necessary when you connect your computer for the first time.
NOTE:
•Some signals may take time or not be displayed correctly
•The Auto Adjust function does not work for component or video signals.
•If the Auto Adjust operation cannot optimize the RGB signal, try to adjust Clock and Phase manually. See page 95.

 Adjusting Pincushion or Barrel Distortion (Pincushion)
If pincushion or barrel distortion become conspicuous, adjust with [Pincushion].
Reference
•Pincushion or barrel distortion in this projector
The amount of pincushion and barrel distortion in this projector is 2% or less (TV distortion) in each of the
horizontal and vertical directions (for screen sizes of 40 inches to 100 inches).
As an example, the amount of distortion with a screen size of 60 inches (121.9 cm/48.0” W x 91.4 cm/36.0” H) is
within approximately 12 mm/0.47” in the horizontal direction and within approximately 9 mm/0.35” in the vertical
direction. When this projector is used with a 60-inch screen size, the amount of pincushion and barrel distortion
is at a minimum.
a: 1% or less of the screen height
(2% or less as TV distortion)
b: 1% or less of the screen width
(2% or less as TV distortion)
1Press the 3D REFORM button of the projector or the remote control.
The [Pincushion] screen will appear.
When the amount of pincushion or barrel distortion exceed 2% (TV distortion), please check whether the projector
and screen setup conditions are suitable.

the image even when the [Bottom] is adjusted.
•In the [Pincushion] screen, when the [Bottom] adjustment value is less than 0, a small portion  can be lost at the bottom area
of the image. To display the lost portion, use the [Digital Zoom] function to reduce the size of the projected image*.
•When [Cornerstone] or [Keystone] has already been adjusted, selection of [Pincushion] will not be possible. To display
[Pincushion], return the adjustment values of [Cornerstone] or [Keystone] to the factory shipping conditions.
*Each note for [Top] and [Bottom] is reversed when the [Ceiling Rear] or [Ceiling Front] is selected in [Orienta-
tion] .
