• You can correct the vertical keystones. However,
their adjustment ranges are limited in such
correction.
Important:
• 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 condition, input signal and aspect
settings in MENU.
• 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.
