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
