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.
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.
