LENS SHIFT
The default height for positioning the projector is at the centre of your screen.
However, you can set the projector above or below the centre and adjust the image
using the ‘Lens Shift’ facility to maintain a geometrically correct image.
As with vertical positioning, the default horizontal position of the projector is at the
centre of the screen. However, the projector can be mounted to the left or right of
image centre and the ‘Lens Shift’ function used to centre the image on screen.
