The adjustable ranges for 3D Reform are as follows:
CORNERSTONE
KEYSTONE
* The following are conditions under which the maximum angle is achieved:
• When the lens shift is set to the center
When the lens shift is used and yet the image is not displayed in the center of the screen, the adjustable range
will be increased or decreased.
• Image is projected in maximum wide with the zoom
NOTE:
• Even when the projector is turned on, the last used correction values are applied.
• If the Cornerstone screen is unavailable (grayed), reset the current correction data. The Cornerstone function becomes avail-
able.
• The range of keystone correction is not the maximum tilt angle of projector.
NOTE: Using [KEYSTONE] correction can cause the image to be slightly blurred because the correction is made electronically.
