5.7 Using X-PORT™ modules
X-PORT™ modules allows for extra functionality with the projector. This includes more con-
nectivity as well as additional image processing.
Functionality may include extended connectivity (like 3G-SDI and HDMI 3D) and additional 3D
format support (like Blu-Ray frame packed, dual input sources, double flash 3D etc.)
Please refer to Chapter 6.4 for information on multi channel 3D sync.
5.7.1 X-PORT DCC120
X-PORT DCC120 is an X-PORT 1 module (post processing) adding additional 3D capabilities
and multi-projector synchronization capabilities to the system.
5.7.1.1 3D formats supported
By using X-PORT DCC120 the following 3D format will then be supported:
Dual head input: When “Dual head” is enabled, the projector will combine the signals from
DVI1 and DVI2 (or HDMI1 and HDMI2), place them beside each other and interpret it as a
single source. The two sources need to have the same resolution. For example, if both inputs
are 1920x1200 @ 60Hz, the combined dual head source will be seen by the projector as a
single 3840x1200 @ 60Hz source. If, now, 3D mode is set to side-by-side, the projector will
take the left half of this combined image, which is in fact the source on DVI1, and use it as
the left eye source. The same goes for DVI2 being the right eye source.
Side-by-side : In side-by-side 3D, each input frame is divided in half and the left half of the
frame is used as the left eye frame and the right half of the input frame is used as the right
eye frame. This makes the output width become half of the input width. If, for example, the
input is 1920x1200 @ 60Hz, the output will be 960 x 1200 @ 120Hz.
Frame sequential
: n frame sequential 3D, every other frame is interpreted as the left eye
frame and the other input frame is interpreted as the right eye frame. To ensure that the
projector chooses the correct frames as the left eye and right eye frames, a 3D sync signal
should be connected from the IG’s display adapter DIN connector to the projector’s BNC
sync-in connector. If such a signal isn’t present, the projector will choose the first input frame
as the left eye frame and the next input frame as the right eye frame. This will be wrong half
the times the signal is acquired.
