Keystone Correction (Correcting Trapezoidal Distortion)
Correcting Trapezoidal
Distortion
When the image is projected either from the
top or from the bottom towards the screen at
an angle, the image becomes distorted
trapezoidally.
The function for correcting trapezoidal distor-
tion is called Keystone Correction.
This projector detects inclination of the upper
and lower sides and corrects trapezoidal dis-
tortion of the image automatically.
Note
•Automatic Keystone Correction may not work
well in some cases, such as when the screen
is leaning, temperature is extremely high or
low, or zooming is at maximum or minimum.
In these cases, fine adjust the Keystone Cor-
rection following the procedure below.
•You can select “Auto” or “Manual” for the
Keystone Correction mode. (See page
44
.)
•The Keystone Correction can be adjusted up
to an angle of approximately ±12˚ when the
Keystone Correction mode is set to “Auto”,
or approximately ±35˚ when set to “Manual”
(when the picture display mode is set to
“NORMAL” (see page
40
)). Therefore, the
actual screen can be diagonally set up to
that angle as well.
