Setting up your projector (continued)

Adjusting the position of the projected image

To adjust the position of the projected image on the screen, use the LENS SHIFT dial.

1.Rotate the LENS SHIFT dial inside the top cover of the projector to adjust the image position.

Rotating the dial clockwise (or counterclockwise for a ceiling-mount projector) moves the image up.

Rotating the dial counterclockwise (or clockwise for a ceiling-mount projector) moves the image down.

Be careful not to be caught in the opening in the lens while the lens is moving.

While the lens shift is working, the screen may flicker.

Projected images may become distorted, have decreased resolution, or have shadows at their corners if they are positioned close to the top (or bottom in the case of a ceiling-mount projector).

Correcting skewed or distorted image

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.Rotate the adjustment feet for fine adjustment.

Important:

Don’t transport the projector with its adjustment feet extended. Otherwise the adjustment feet may be damaged.

When fine streaks are seen on projected images

This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace the focus a little. (See page 18 or 23 for focus 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.

With the INSTALLATION menu: (See page 29 for menu setting.)

1.Display the INSTALLATION menu.

2.Select KEYSTONE by pressing the or button.

3.Equalize the widths at the top and bottom of the screen by pressing the t or button, viewing the screen.

button.

In the keystone adjustment, you can obtain an optimum result when the LENS SHIFT dial is at the center position.

When the keystone adjustment is carried out, the adjustment value is indicated. Note that this value doesn’t mean a projection angle.

When the keystone adjustment takes effect, the resolution decreases. In addition, stripes may appear or straight lines may bend in images with complicated patterns. They are not due to product malfunctions.

When the keystone adjustment is carried out, the image may not be displayed correctly because of the type of input signal.

When the keystone adjustment is performed, the displayed image may be distorted.

Depending on the installation conditions of the projector and the screen, a perfect rectangular image and the proper aspect ratio may not be obtained.
