If it is not possible to position the projector perpendicular to
the projection screen (so that the lens center and screen cen-
ter are aligned with each other) you can use the mechanical
lens control at the top of the projector to shift the projected
image vertically:
•insert the provided hex wrench into the vertical lens
shift adjuster
•turn the wrench to shift the lens in the desired direc-
tion
The Nero 3D provides up to 50% of vertical lens shift up. For example, with a 16:9 150
in. diagonal size screen, you can shift the image up to 0.93 m (36.8 in.) above the
screen center (see “Projection Distances” on page 40).
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
If the tilt is not excessive, you can use the Keystone function of the projector to cor-
rect the image shape. See “Keystone” on page 29.
Note: Keystone correction may cause artifacts in the image and may not be available
when displaying specific 3D content (see Table 4.2).
Zoom and Focus
The Nero 3D provides motorized Zoom and Focus controls. You can access these
adjustments through the remote control directly:
•F1 key for optical Zoom
•F2 key for Focus
See “F1-F2 Keys” on page 31 for details.
Connections
Proceed as follows to connect the Nero 3D to video sources, control devices, screen
control systems, 3D sync emitter and AC power.
When connecting your equipment:
•turn off all equipment before making any connections
•use the correct signal cables for each source
•make sure cables are routed so that people are not impeded or become a trip
hazard
•ensure that the cables are securely connected (tighten the thumbscrews on
connectors that have them)
Video
Often the sources (Blu-ray Players, Set Top Boxes, Game Consoles and so on) have sev-
eral outputs. Choose HDMI whenever possible.
•HDMI The major benefits of this signal type are:
◦best image quality, because the signal is carried in the digital domain
