*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" (x page 38).
*2 When [VERTICAL KEYSTONE] and [HORIZONTAL KEYSTONE] are used simultaneously, correction cannot be made exceeding total of 55°.
