Adjusting the Projection Distance
• Refer to pages 19 and 20 about the function of Keystone correction and placement of projector using the correction.
• Decide the placement of the projector referring to the figures on the table and the diagram below according to the size of
your screen and Input Signal.

• The aspect ratio of the projected image shifts slightly when the
lens shift is at a position other than the top position.
• The aspect ratio of the projected image also shifts slightly
when the “H Keystone” and “V Keystone” functions are
adjusted simultaneously.
• Keystone correction cannot be applied to On Screen Display.
• When Keystone correction is applied, the resolution of image
can be deteriorated to some extent.
• There are errors of
±
3% in the formulas below.
