Installing the Projector against the Screen
The projector should be placed so that the center line of the lens is at a right angle to the screen as shown in the following
figures.

Trapezoidal-distortion correctable maximum angle
The projector has a function to correct the trapezoidal distortion of the projected image on the screen.
To correct this distortion, use the KEYSTONE buttons on the projector. (Refer to “Removing the Trapezoidal Distortion of the
Image” on page34.) Also, correction is possible by using the “Keystone” menu. (Refer to “Setting and Adjusting Other
Functions (OPTIONS)” on page53.)

Installing the Projector
Projection Distance and Screen Size
•The projector’s projection lens is a zoom lens of about 1.5 x. The screen size at the maximum enlargement is 1.5 times that
of the minimum size.
•The projection distance that can be focused is 2.5 to 20 m. Install the projector within this range.
*Also, refer to the table of “Relationship between Projector Distances and Projector Screen Size” on page 19 as a reference.
Notes
•For detailed relationship between projection distances and projection screen sizes, refer to Appendix A. The relationships for
both 4:3 and 16:9 ratios are listed there.
•When installing a screen, use a 4:3 aspect-ratio picture.
•(A 16 : 9 aspect-ratio picture is projected based on the width of the range in which a 4:3 aspect-ratio picture is projected.)
•The diagonal length of a 16:9 aspect-ratio screen is about 91.8% that of a 4:3 aspect-ratio screen. This value is only a guide
(reference).
•If sunlight or lamp light strikes the projection screen directly, the picture tends to become pale and dim. Use a curtain or
other means to shield the light.
•Set the projector horizontally on a surface that is within the range of adjustable angles (up/down adjustment angle: +7° ;
horizontal adjustment angle: ±1.5°).
•If the keystone is adjusted, the projected screen becomes smaller.
•When hanging from the ceiling, use a dedicated hanging fixture (not supplied).

Center line of the lens
Install the projector so the lower edge of the projection screen is at the
same height as the lens' center line.
