3.5 Projector positioning
Positioning the projector
The projector should be installed at right angles (horizontally and vertically) to the screen at a distance PD.
Note the distance (A) between lens centre and table surface is slightly variable. This distance (A) is nominal
223 mm in case all feet are turned in completely and the vertical lens shift is set to zero (0).

On axis / off axis projection
The position of the projector with reference to the screen may also be different depending on the installation.
Basically the projector can be positioned in On-Axis or Off-Axis configuration. On-Axis configuration means
that the projector is positioned so as to have the centre of the lens coinciding with the centre of the screen.
Off-Axis projection is obtained by shifting the lens up, down, left or right. Several parameters can be calculated
determining the position in any installation.
Formula to calculate the distance CD for On-Axis projection:
CD = SH/2 + B - A
