Sharp DT-300 Adjusting the Projection Distance

Setup

Adjusting the Projection Distance

•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.

Center of the screen

(a) Maximum projection distance

(b) Minimum projection distance

(d)

Placement range

(e)

(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.

(c)(f)

±10°

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.
