Projection distances by the type of projection lenses (for PT-D7700U)

• For the screen aspect ratio of 4:3 Units: m (feet/inches)

• The projection distances listed here involve an error of ±5%.

• Keystone distortions are corrected in the way the screen size becomes smaller than the original one.

Projection distances by the type of projection lenses (optional)

Every type of optional projection lenses has a different projection distance to achieve the same screen size. Select

and purchase a projection lens most suitable to the size of your location referring to the following tables and the
