2.6  Lens Offset, Picture Zoom and Focus
Lens Offset
The optimum image can be obtained when this projector is place perpendicular to the projection screen. The lens
offset is xed to 50%, that means that the projector can be placed either at the top or at the bottom of the picture
as shown in the below picture.
This unit comes with a vertical offset xed to +50%. It means that the optimal position of this projector
is at the bottom or top of your screen. Placing the unit in one of these positions prevents the use of
electronic trapezoidal correction and will give the best picture quality.
If the projector is not installed perpendicularly to the screen, use keystone correction to fulll your screen. You can
also use up to +/- 40° up and down keystone correction. Note that using keystone correction is not recommended
if you want the best image quality.
