•
The projected image becomes smaller after correcting distortion. Increase the projection distance to
fit the projected image to the screen size.
•
Install the projector parallel with the screen without any loss in image quality. If you cannot install the
projector parallel to the screen, adjust the shape of the image using H/V-Keystone correction.
•
When correcting distortion, rotate the lens shift dial to adjust the lens position to the top edge. If the
lens position is incorrect, the projection screen may be warped.
Correct automatically (Auto V-Keystone)
When the projector detects that it is tilted during projection, Auto V-Keystone automatically corrects any
vertical keystone distortion. Two seconds after the projector is tilted, it displays an adjustment screen and
then automatically corrects the projected image.
Auto V-Keystone can correct the projected image distortion in these conditions:
•
Projection angle is less than 30° up or down.
•
Projection is set to Front .
