Note
z
The values obtained from the above formulas may contain slight errors.
z
The throw ratio is based on the value during projection onto a 3 810 mm (150”) screen size.
z
When GEOMETRY or KEYSTONE adjustment is used, compensation is made so that the screen size
becomes smaller than the specified size.
