Keystone Adjustments

Auto / Manual Keystone Adjustment
The LED Showtime 3D has the ability to
autocorrect any vertical Keystone effect.
This setting is on by default. To change it to
manual adjustment, go into Picture Settings,
and change the Keystone option from Auto
to Manual. The Keystone correction can be
controlled by the remote supplied with your
LED Showtime 3D.
What is Keystoning?
“Keystoning” occurs when a
projector is aligned non-per-
pendicularly to a screen, or
when the projection screen
has an angled surface. The
image that results from one
of these misalignments will
look trapezoidal rather than
square.
