You can correct the vertical and horizontal keystones. 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.
•
Images may not be projected in a shape of a regular rectangle or with its aspect ratio 4:3,
depending on the installation conditions of the projector and the screen.
•
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.
