Dukane 8761A User Manual page 52

The adjustable ranges for 3D Reform are as follows:
Cornerstone
Keystone
* The following are conditions under which the maximum angle is achived:
• Image is projected in Wide (Zoom lever)
• Resolution is XGA
Higher resolution than XGA narrows the adjustable range.
• Menu items should be set as follows:
Aspect Ratio ........... 4:3
Screen Type ........... 4:3
• Horizontal and Vertical are adjusted separately.
A combination of both adjustments narrows the adjustable range.
• When "4:3 Fill" is selected in Aspect Ratio, "Cornerstone" and "Horizontal Keystone" are not available.
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.
To use the previous correction setting values after changing projection angle, select "Manual" in "Keystone" from the menu. See
page 90.
NOTE: The 3D Reform feature can cause an image to be slightly blurred because the correction is made electronically.
