AUTO KEYSTONE Correcton
The AUTO KEYSTONE correction feature will correct the vertical distortion of a projected image on the screen.
No special operation required. Just place the projector on a flat surface.
NOTE: When using the AUTO KEYSTONE function, heed the following:
• The AUTO KEYSTONE correction will take effect in 2 seconds after changing the projection angle during projection.
• The left and right, or horizontal keystone distortion is not available.
Place the projector so that the lens surface is parallel to the screen.
Also, adjust the height to keep the projector level by rotating the rear feet.
TIP: To turn off the AUTO KEYSTONE function, from the menu select [SETUP] → [GENERAL] → [AUTO KEYSTONE] and select [OFF].
( → page 60 ) Even when the menu setting for [AUTO KEYSTONE] is turned on, [KEYSTONE] can be adjusted manually.
NOTE: The AUTO KEYSTONE Correction feature can cause an image to be slightly blurred because the correction is made elec-
tronically.
