Correcting keystone distortion
Keystone distortion is corrected automatically when the projector’s automatic
setup function is used, but this correction will not apply if the screen itself is
tilted. In such cases, you can correct the keystone distortion manually with
the following procedure.
#Select “KEYSTONE” from the MAIN MENU screen, and then press the
ENTER button.
$Press the
II
or
HH
buttons to correct the keystone distortion.
Picture condition Operation
Press the
HH
button.
Press the
II
button.
%Press the MENU button to return to the previous screen.
NOTE:
BIf you press the AUTO SETUP button after correcting the keystone
distortion manually, the automatic keystone correction function will operate
and the corrected picture will return to its previous incorrect condition. To
prevent this from happening, you can set “AUTO KEYSTN” in the
OPTION1 menu to “OFF”.
BKeystone distortion can be corrected to ±30° of the angle of tilt for the
projector. However, the greater the correction amount, the more the
picture quality will deteriorate, and the harder it will become to achieve a
good level of focus. To obtain the best picture quality, set up the projector
and screen in such a way that the amount of keystone correction required
is as minimal as possible.
BThe picture size will also change when correction of keystone distortion is
carried out.
%Use the D.ZOOM +/- buttons to
change the enlargement ratio.
The enlargement ratio can be
changed within the range of x1 to
x2, in steps of 0.1.
NOTE:
BWhen RGB signals are being
input, the enlargement ratio can
be changed within the range of
x1 to x3.
