Adjusting the Screen Image
14
When the projector is tilted, it will cause keystone distortion to appear in the image. This distortion can be
corrected using the keystone correction function, as long as the vertical angle of tilt is within a range of
approximately 15º.
Procedure
Correcting Keystone Distortion
•
When keystone correction is used, the projected image will become smaller.
•
The keystone correction settings are memorized. If you change the position or angle of the
projector, you may need to readjust the keystone correction settings.
•
If the images become uneven in appearance after keystone correction is carried out, decrease
the sharpness setting. (p.23, 24)
•
If the value displayed in the gauge on the screen stops changing when keystone correction is
being carried out, it indicates that the limit for keystone correction has been exceeded. Check
that the projector has not been set up at an angle that exceeds the proper limit.

Keystone correction can be carried out using either the projector's control panel or the configuration menu.
The following explanation describes how to correct keystone distortion using the projector's control panel.
