Connections - Sim2 Sirio User Manual

If it is not possible to position the projector perpendicular to the projection screen (so
that the lens center and screen center are aligned with each other) you can use the
motorized vertical shift (see page 31) to shift the projected image vertically.
The SIRIO provides up to 60% of vertical lens shift up. For example, with a 16:9 150 in.
diagonal size screen, you can shift the image up to 1.12 m (44.4 in.) above the screen
center (see "Projection Distances" on page 42).
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
correct the image shape. See "Keystone" on page 31.
Note: Keystone correction may cause artifacts in the image and may not be available
when displaying specific 3D content (see Table 4.2 on page 24).
Zoom and Focus
The SIRIO 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 33 for details.

Connections

Proceed as follows to connect the SIRIO 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, DVD Players, Set Top Boxes, Game Consoles and so
on) have several 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 throughout the
entire signal path
◦highest available resolution, because video sources can deliver full resolution
content via HDMI only
◦availability of 3D content, because most 3D compatible sources deliver 3D content
