Step 5 Adjusting Keystone Distortion
To correct keystone distortion (Keystone adjustment), press the KEYSTONE
button.
Two types of adjustment are available: horizontal/vertical adjustment and corner
adjustment.
Use horizontal/vertical keystone adjustment to adjust image width or height
distortion separately, and use corner adjustment to adjust the position of each
corner of the image.
For instructions on switching keystone adjustment, refer to “Keystone” (
P108 ).
■ Horizontal/Vertical Keystone Adjustment
1
Press the KEYSTONE button on the remote control or projector to display
the horizontal-vertical keystone adjustment window. (When [Keystone] is
set to [Horizontal-vertical keystone].)
• Keystone correction may not be effective in some lens shift positions.
• If keystone distortion is excessive and cannot be fully corrected, straighten the
projector so that it faces the screen directly.
• Signals are processed digitally when keystone distortion is corrected. The image may
look different from the original one. In addition, the aspect ratio of the image may
change.
