1. Press the ASPECT button.
• Every time the ASPECT button is pressed, the aspect mode changes from AUTO to 16:9, to REAL, to FULL,

Important:
• You can correct the vertical and horizontal keystones at the same time. However, their adjustment ranges are
limited in such correction.
• 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.
• 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.
• When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of
input signal.
• When horizontal and vertical keystone adjustments are performed in combination, the adjustable range becomes
narrower than in the case when they are performed separately.
• 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.
• In the keystone adjustment with the option lens, the aspect ratio of 4:3 may not be obtained.
