This projector detects its own degree of tilt and corrects
the keystone distortion automatically.

ON : Active
This projector detects its own degree of tilt and corrects
the keystone distortion automatically (“
REALTIME
KEYSTONE ”). However, keystone distortion may still
affect the images in some cases (e.g. when the projector
is tilted slightly and the tilt is corrected slowly by hand or
when the screen itself is tilted). In such cases, set
“
REALTIME KEYSTONE ” to “ OFF ” and correct the
vertical keystone distortion manually.

Image Operation
NOTE:
• You can correct the distortion ± 30 degrees from the
plane. For a better quality image, installing the projector
with a minimum of distortion is recommended.
• The distortion of the Main menu screen is not
correctable.
• The result of the keystone correction will affect the
aspect ratio and the size of the image.
• You can correct the keystone distortion manually when
“ REALTIME KEYSTONE ” is set to “ ON ”.
However, when you turn on the power, the amount of
correction will be reset and “
REALTIME KEYSTONE ”
will function again if the tilt is different from the last time
you used the projector. If you correct the keystone
distortion manually when “
REALTIME KEYSTONE ” is
set to “ OFF ”, the amount of correction will be stored by
the projector even after the power is turned off.
