Note
z
The values obtained from the above formulas may contain slight errors.
z
The throw ratio is based on the value during projection of a 3.81 m (150") size image.
z
When GEOMETRY or KEYSTONE adjustment is used, compensation is made so that the projected image size
becomes smaller than the specified size.
