4.1 Adjusting the projector ’ s position
Positioning the projector
To determine where to position the projector, consider the size and shape of your screen, the location of your
power outlets, and the distance between the projector and the rest of your equipment. Here are some general
guidelines:
• Position the projector on a flat surface at a right angle to the screen.
• Position the projector to the desired distance from the screen. The distance between the lens and the
screen, the zoom settings, and the video format determine the size of the projected image. For projection
distances of each lens, see chapter
“ Lenses ” , page 13.
• 360 degree free orientation installation:

4.2 Adjusting the image position on the screen
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.
Shift range
The lens can be shifted with respect to the DMD (P) which result in a shifted image on the screen (Off-Axis). A
100% shift means that the centre point of the projected image is shifted by half the screen size. In other words,
the centre point of the projected image falls together with the outline of the image in an On-Axis projection.
Due to mechanical and optical limitations it's recommended to keep the shift values within the field of view (F)
as illustrated below. Within these shift ranges the projector and lens perform excellently. Configuring the
projector outside these shift ranges will result in a slight decline of image quality.
G60 Vertical Shift range: 100%
G60 Horizontal Shift range: 30%
