*1 When [VERTICAL KEYSTONE] and [HORIZONTAL KEYSTONE] are used simultaneously, correction cannot be made exceeding total of 55°.
Note
f When [GEOMETRY] 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] 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.
