Important
• For proper KEYSTONE-mode adjustment results, reset the lens to the factory-adjusted position using LENS SHIFT RESET in
the INSTALLATION 1 menu in the ADVANCED menu before carrying out KEYSTONE-mode adjustment.
• When the KEYSTONE-mode adjustment takes effect, the resolution decreases. In addition, stripes may appear or straight lines
may bend in images with complicated patterns. They are not due to product malfunctions.
• When the KEYSTONE-mode adjustment is performed, the displayed image may be distorted.
• Depending on the installation conditions of the projector and the screen, a perfect rectangular image and the proper aspect
ratio may not be obtained. Slight distortion can be corrected by the CORNERSTONE-mode adjustment.
• Noise may appear on the screen during the KEYSTONE-mode adjustment because of the type of the video signal being pro-
jected and the setting values of the KEYSTONE-mode adjustment. In such cases, set the KEYSTONE-mode adjustment values
in the range where the image is displayed without noise.
• When you carry out the KEYSTONE-mode adjustment and the CURVED-mode adjustment in combination, the adjustment
range becomes narrower than that in the case where you carry out these adjustments individually. When setting the KEY-
STONE-mode adjustment value to 11 or larger, you cannot use the CURVED-mode adjustment.
• When carrying out the KEYSTONE-mode adjustment while the option lens is in use, you may not be able to obtain a perfectly
rectangular image or the correct aspect ratio. Slight distortion can be corrected by the CORNERSTONE-mode adjustment.

About blanking temporarily
