*1 Cannot correct [VERTICAL KEYSTONE] and [HORIZONTAL KEYSTONE] if the total exceeds 55° when used at the same time.
Note
f When [GEOMETRY(2D)] is used, the focus of the entire screen may be lost as correction increases.
f Make the curved screen a circular arc shape with one part of a perfect circle removed.
f Adjustment range of the [GEOMETRY(2D)] items may not match the listed projection range depending on the projection lens. Use this
projector within the projection range, otherwise the correction may not work.
f [GEOMETRY(2D)] can be selected only when a 2D image is displayed. The setting becomes invalid while a 3D image is displayed. When
executing the keystone correction while displaying a 3D image, set with [KEYSTONE(3D)].
However, if [3D SYSTEM SETTING] is set to [DUAL (LEFT)] or [DUAL (RIGHT)], the keystone correction becomes possible by selecting
[GEOMETRY(2D)] even during the 3D image display.
