[GEOMETRIC CORRECTION]
MODE
Set pattern for correcting distortion. If [OFF] is selected, the [GEOMETRIC CORRECTION] becomes ineffective.
If you need to change either the [MENU ANGLE] or [MENU POSITION], make sure to change these before performing
the [GEOMETRIC CORRECTION]. If either of them is changed after performing the [GEOMETRIC CORRECTION],
corrected values will be reset to the default values.
KEYSTONE
Correct distortion in horizontal and vertical directions.
HORIZONTAL ��������� Adjustments when projecting from a diagonal direction to the

VERTICAL �������������� Adjustments when projecting from the top or bottom direction to
the screen�

NOTE:
• When power is supplied to the device, the adjustment value of the [KEYSTONE] used previously is retained even if the gradient
of the device is changed.
•
As electrical correction is carried out by [KEYSTONE], the brightness may be reduced or the screen quality may deteriorate
sometimes.
