Setup & Connections 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.

Setup & Connections
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.
