Adjustment Using The Cornerstone Mode - Mitsubishi Electric DLP WD8200LU User Manual

Setting up your projector (continued)
• 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 projected 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
KEYSTONE-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.
