Auto V-Keystone Correction
When the image is projected either from the top
or from the bottom towards the screen at an angle,

The function for correcting trapezoidal distortion
is called Keystone Correction.
This projector is equipped with an "Auto V-Key-
stone Correction" function that automatically cor-
rects any trapezoidal distortion within the pro-
jected image. The correction is made automatically
provided the vertical incline or decline is within
±12 degrees.

rection function, set "Auto V-Keystone" on
the "SCR-ADJ" menu to "Off".
