Manually Correcting Keystone Distortion
This projector is equipped with an automatic keystone correction function
that detects the vertical angle of the projector during projection and
automatically corrects vertical keystone distortion. If you would like to
make further fine adjustments after automatic keystone correction has been
carried out, or if the projector is tilted horizontally, you can carry out
keystone correction manually.
This projector is equipped with the following two keystone correction
functions. Use whichever function is appropriate for the keystone
distortion that appears.
• Auto Keystone/H/V-Keystone
Automatic keystone automatically corrects keystone distortion when the
projected images are vertically distorted.
H/V-Keystone can be used to make fine adjustments to the results of
automatic keystone correction and to correct horizontal keystone
distortion.
The keystone correction function lets you easily correct keystone
distortion that has occurred after moving the projector, simply by using
buttons on the projector's control panel.
See "Automatic keystone correction" p.46
"Vertical correction and horizontal correction" p.47
"Height Correction" p.48
• Quick Corner:
This correction function is used when both horizontal and vertical
keystone distortion occurs in the projection area to adjust the projection
area so that it fits the screen exactly. p.49
TIP
If the projector is tilted within a range of approximately 30º up or
down, keystone correction is carried out automatically. If the
projector is tilted within a range of approximately 40º up or down or
20º to the left or right, manual keystone correction can be carried out.
However, the applicable angles will become smaller under the
following conditions.
• If the projector has been tilted both horizontally and vertically
• If an optional projection lens has been fitted
• When the zoom is set to "W"
