*1 The throw ratio is a value calculated by dividing the projection distance by the projected image width.
For details of the projection distance and the projected image width, refer to “Projected image and throw distance” (

page 37).
*2 When [VERTICAL KEYSTONE] and [HORIZONTAL KEYSTONE] are used simultaneously, correction cannot be made exceeding total of 55°.

When [SCREEN ADJUSTMENT] 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.
