Connections
Proceed as follows to connect the NERO4 to video sources, control devices, screen
control systems and AC power.
When connecting your equipment:
turn off all equipments 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)
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 con-
tent via HDMI only
optimization of several image parameters (color space, aspect, signal range, over
scan), thanks to auxiliary information (AVI infoframe) sent by the source device to-
gether with the signal.
If your source has dual HDMI outputs, we would recommend direct connection to the
projector from one of the HDMI connections and the second HDMI output to the in-
put of an appropriate AV receiver/processor for audio.
Sources with a DVI-D output can be connected to the HDMI input of the projector us-
ing a suitable DVI-D to HDMI cable. In this case no auxiliary information is sent from
the source to the projector.
Note:
HDMI uses a code known as HDCP (High-bandwidth Digital Copy Protection),
which protects the recorded supports from being copied illegally. The connection be-
tween the source and display requires that the two devices perform a handshake and
exchange code keys before being able to display an image. The InstaPort technology
allows a simultaneous pre-authentification of every attached device at the same it is
connected, reducing drastically the time required for HDMI source switching. For this
reason you may note a slight delay before the image appears on the screen, but it is
perfectly normal.
DispalyPort
is a digital display interface developed by the Video Electronics
Standards Association (VESA). The interface is primarily used to connect a video
source to a display device. DisplayPort can be used to transmit audio and video
simultaneously, but each one is optional and can be transmitted without the
other.
Graphics RGB
Input for Personal Computer and other sources that outputs RGB or
YPrPb signals. These sources must be able to provide separate H/V sync or com-
posite H+V sync.
