Adjusting the Projection Distance

Setup

•

Refer to pages

33

and

34

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.

(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.

Note

•

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.

•

When adjusting

“

H Keystone

”

and

“

V Keystone

”

at the same

time, the values of adjustable angles for each setting

become smaller.

•

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.
