Correcting Trapezoidal

When the image is projected either from

distorted trapezoidally. The function for
correcting trapezoidal distortion is
called Keystone Correction.
Note
• The Keystone Correction can be adjusted up
to an angle of approximately ±40 degrees and
the screen can also be set up to an angle of
approximately ±40 degrees (when the resize
mode is set to "NORMAL" (see page 30)).

Info

these cases, fine adjust the Keystone Correc-
tion following steps 1 to 3.
