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.

•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.
•While a 3D image is displayed, the keystone adjustment is unavailable.
