Ceiling Mounting
Invert the projector and suspend it from the ceiling using a specific brkt4 bracket, de-
scribed in the chapter 10, at page 52.
Orientation
By default, the NERO4 is configured for a Front installation (projector installed upright
and in front of the screen). If the projector is installed behind the screen or inverted,
you can use the image orientation function of the projector .
Vertical Lens Shift
Ideally, the projector should be positioned at a right angle to the screen and in such a
way that:
the lens center and screen center are aligned with each other
the projected image fills the screen perfectly
Keystone
If the projector is ceiling-mounted and the screen is lower than the projector, you may
need to tilt the projector by adjusting the ceiling mount. If you do so:
the top and bottom borders of the image will be unequal in length
the sides of the image will be inclined
