3. Convenient Features
The adjustable ranges for 3D Reform are as follows:
HORIZONTAL VERTICAL
CORNERSTONE
Max. +/− 35° approx. Max. +/− 30° approx.
KEYSTONE
* The following are conditions under which the maximum angle is achieved:
• When the NP18ZL lens is used
• 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), press and hold the 3D REFORM button for a minimum of 2 seconds to reset
the current correction data. The Cornerstone function becomes available.
• Turning on the projector will reset the previous correction setting values and correct distortion anew if the projection angle is
changed from the last use.
If the projection angle is the same as in the last use, the previous correction setting values are retained in the memory.
• The range of keystone correction is not the maximum tilt angle of projector.
NOTE: Using 3D Reform correction can cause the image to be slightly blurred because the correction is made electronically.
