Cannot correct [VER

TICAL KEYSTONE] and [HORIZONTAL KEYSTONE] if the total exceeds 55° when used at the same time.
Note
 z When [GEOMETR

Y] is used, the focus of the entire screen may be lost as correction increases.
 zMake the curved screen a circular arc shape with one part of a perfect circle removed.
 zAdjustment range of the [GEOMETR

Y] items may not match above due to the projection lens. Use this 
projector within the projection range, otherwise the correction does not work.
