Projection distance according to the projector lens.
For the projection distances for projection [Lenses (optional)], refer to the operating instructions [Installation]
provided with The projector. Or check the diagonal dimension (m) of your screen and calculate the projection
distance using the following formula.

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.
