Lens Offset
This projector uses a fixed offset lens.
The fixed offset is +57.5% of screen height. Therefore the centre line of the projector lens would normally
be located either below the bottom on the screen or mounted inverted above the top of the screen.
A small amount of manual vertical and horizontal shift is also available see below.
Adjusting the vertical image position
The vertical image height can be adjusted around 14.5% for XGA and 12% for WUXGA of the offset
position.
Note that the maximum vertical image height adjustment can be limited by the horizontal image position.
For example it is not possible to achieve the maximum vertical image position height detailed above if the
horizontal image position is at maximum. Please consult the Shift Range diagram below for further
clarification.
Adjusting the horizontal image position
The horizontal image position can be adjusted to a maximum of 6.4% for XGA and 5% for WUXGA of the
image width. Note that the maximum horizontal image height adjustment can be limited by the vertical
image position. For example it is not possible to achieve the maximum horizontal image position if the
vertical image position is at maximum. Please consult the Shift Range diagram below for further
clarification.
