Setting up the screen

Install the screen perpendicularly to the projector. If the screen can not be installed in such a way, adjust the 

projection angle of the projector. (See below.)

•  Install the screen and projector so that the projector’s lens is placed at the same height and horizontal position of 

the screen center. 

•  Do not install the screen where it is exposed to direct sunlight or lighting. Light directly reflecting on the screen 

makes the projected images washed-out and hard to view. 

SCREEN SIZE

You can keep the image display area within the screen by setting SCREEN SIZE in the IMAGE menu according to the 

size of the actual screen. 
When setting SCREEN SIZE to CINEMA SCOPE(2.35:1):

•  CinemaScope size movies are projected in the full screen.

•  Set ASPECT in the FEATURE menu to 16:9 when displaying Vista-size images. In this case, they are squeezed horizontally.

•  When ASPECT in the FEATURE menu is set to AUTO and 480p, 720p, or 1080i signal is input, the part for 

displaying subtitles is not projected. Then, set SCREEN SIZE to 720P(16:9) and adjust the image position using 

VERTICAL LOCATION of the IMAGE menu. (To display the menu on the screen, adjust SHUTTER (U) of USER in 

the SIGNAL menu to position the menu.)

Basic setup

Determine the distance from the screen to the projector according to the size of the images to be projected. (See 

page 12.)

•  Do not place this projector on a carpet or blanket because the exhaust vent and the intake vent on the bottom 

surface are blocked and the projector would heat, causing a breakdown or fire. 

•  Depending on the installation conditions, warm air that is emitted from the exhaust vents may flow into the intake 

vent, causing the projector to display “TEMPERATURE!!” and then stop projecting images.  

Adjusting the projection angle

This projector is provided with three feet for 

adjusting the projection angle on the bottom 

surface. Adjust the projection angle depending on 

the position of the projector. 

Adjustment of the projection angle

For the best projection, project images on a 

flat screen installed at 90 degrees to the floor. 

If necessary, tilt the projector using the two 

adjustment feet on the bottom of the projector. 

1.  Tilt up the projector to the appropriate angle. 

2.  Press the foot adjustment buttons next to the 

adjustment feet (rear), and the adjustment feet 

will come out. 

3.  Release the buttons to lock the adjustment feet 

(rear) to that position.

4.  Rotate the adjustment feet (rear) for fine 

adjustment.

After using the projector:

5.  Put the adjustment feet (rear) back into the 

projector by pressing the foot adjustment buttons.

•  If necessary, rotate the adjustment feet (front) for 

fine adjustment. 

When projected images are distorted to a 

trapezoid:

When the screen and the projector are not placed 

perpendicularly to each other, projected images 

become trapezoidal. If you cannot make the 

projector and the screen perpendicular to each 

other by mechanical adjustments, adjust keystone. 

(See page 18.) 

•  When the keystone adjustment is applied, the 

correct aspect ratio may not be obtained. 

•  When the keystone adjustment is applied, the 

resolution lowers. In addition, vertical stripes ap-

pear and straight lines bend in images with com-

plicated patterns. To prevent such symptoms, 

keep the screen and the projector perpendicular 

to each other as much as possible. 

•  Though the projected image may be distorted 

momentarily when you change the setting value 

of the keystone adjustment, such symptom is not 

a malfunction. 

•  Though the projected image may be distorted 

depending on the setting value of the keystone 

adjustment and the type of the input signal, such 

symptom is not a malfunction. In such a case, 

adjust the setting value within the range where 

the projected image is not distorted. 

•  The setting value displayed at the time of the 

keystone adjustment may vary depending on the 

type of the input signal. 

•  The keystone mode does not function when the 

REAL mode is applied.

•  Displayed image may be distorted during key-

stone adjustment.

VERTICAL LOCATION

You can adjust the vertical position of the displayed image using 

VERTICAL LOCATION in the IMAGE menu.

(Example) To move the displayed image up:

Maximum panel size (WXGA 15:9)

Empty area

Set SCREEN SIZE in the IMAGE 

menu to 720p(16:9)

Empty area

Set VERTICAL LOCATION in the 

IMAGE menu to +6.

•  When you increase the value of VERTICAL LOCATION too much, 

the displayed image may be out of the screen partially.
