4. Convenient Features

The adjustable ranges for 3D Reform are as follows:

	Horizontal	Vertical
Cornerstone	Max. +/– 40° approx.	Max. +/– 30° approx.
Keystone

*The following are conditions under which the maximum angle is achieved:

•When the standard 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 Wide (Zoom lever)

NOTE:

•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.

NOTE: Using 3D Reform correction can cause the image to be slightly blurred because the correction is made electronically.
