Correcting the Horizontal and Vertical Key-
stone Distortion (3D Reform)
Use the 3D Reform feature to correct keystone (trapezoidal) distortion
to make the top or bottom and the left or right side of the screen longer
or shorter so that the projected image is rectangular.
In the following description, 3D Reform (Cornerstone) correction can be
done with the USB mouse or remote control, cabinet buttons.
Using Auto Focus
Press and hold the AUTO ADJUST button on the cabinet or AUTO ADJ
button on the remote control for a minimum of 2 seconds. The focus
pattern will be displayed for a moment and then the best focus will be
automatically obtained.
NOTE: The Auto Functions have two options: Focus and Wall Color Correction.
When the AUTO ADJUST or AUTO ADJ button is pressed and held for a mini-
mum of 2 seconds, either item can be executed. You can decide in advance
which item will be enabled at the time of execution.

ADJ button on the remote control will enable the Auto Adjust feature instead of
