•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.
