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.

Center of the screen		(a) Maximum projection distance
Center of the screen		(b)Minimum projection distance
		(b)Minimum projection distance
	Placement range	(c) Horizontal placement range when projection distance is maximum.
	Placement range	(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.

(d)		(e)

(c)		(f)
	±10°	• The aspect ratio of the projected image shifts slightly when the
	±10°	lens shift is at a position other than the top position.
		lens shift is at a position other than the top position.
(b)		• The aspect ratio of the projected image also shifts slightly

		when the “H Keystone” and “V Keystone” functions are
(a)		when the “H Keystone” and “V Keystone” functions are
		adjusted simultaneously.
		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.
