(1)If the image is shifted to the left or right, move the main unit horizontally. (Align the center of the screen and the center of the projector lens.)

(2)If the image is shifted vertically, move the image up or down with the adjuster. See “Making Adjustments with the Adjust- ers” on Page E-23.

(3)If the image is slanted, adjust by turning the right or left adjuster. See “Making Adjustments with the Adjusters” on Page E-23.

(4)A projection image such as that illustrated in the diagram is the result of the projector not being perpendicular to the screen. Set the projector so that it is pointing straight toward the screen.

(5)The vertical keystone distortion of the projection screen will be corrected automatically. (Auto Keystone Function)

An automatic adjustment will be made approximately 2 seconds after the projection angle has been fixed. When the adjustment is completed, the [Auto Keystone Complete] message will be displayed for about 1.5 seconds.

To make fine adjustments after the automatic adjustment, see “Keystone Manual Adjustment” on Page E-27.

Auto Keystone Function

Keystone distortion arises when the projector is on a slant in the vertical orientation. This projector has an “Auto Keystone” function that detects the vertical slanting and corrects it automatically.

This function is disabled when [Auto Keystone] of the on-screen menu is set to “OFF”. See “Auto Keystone” on Page E-46.

Conditions for Automatic Correction

Automatic correction will operate in the range of 2 to 12 degrees in the upward direction, and 2 to 18 degrees in the downward direction.

Correction is performed only while the image is being projected.

Note:

Correction might not be possible when the screen surface is on a slant, or when the ambient temperature of the projector is extremely high or low.
