• 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 the input signal.

(f)

Placement range

(e)

±10°

(a) Maximum projection distance
(b) Minimum projection distance
(c) Horizontal placement range when projection distance is maximum.
(d) Horizontal placement range when projection distance is minimum.
(e) Vertical placement range when projection distance is maximum.
(f) Vertical placement range when projection distance is minimum.

• 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.
