•
Limited to presenting 32 discrete sources.
•
The combined bandwidth of the downscaled sources on the display cannot exceed 8.5 Gbps.
•
The smallest grid size for multiviewers are 2x2.
•
The multiviewer uses a scaler on a transmitter. A second display in a system may cause a
conflict between displays trying to use the downscaler. System programming must avoid
potential display combinations that may result in a conflict.
•
Source must be progressive.
•
RX output is always RGB 8 bit, regardless of the source being 8, 10, or 12 bits.
•
Bezel correction values are set independently for top, bottom, left, and right side but it
assumes the same correction for each display forming the matrix. Thus, all displays must be
the same and properly aligned without any physical gaps between displays. Refer
Videowall Modes
Videowall modes allow a single source to be stretched and magnified across multiple displays.
The following modes are available:
•
Genlock Wall

Fast Switch Wall

Genlock Wall Mode
The primary benefit of Genlock Wall mode is a synchronized (genlocked) output to all the displays.
•
In this mode, all the receivers are synchronized to the source and therefore to each other.
•
Signals supplied by receivers driving videowall magnifications use unique timing for outputs
based on the original source resolution, display resolution, and number of rows in a videowall
array. They deliver a signal for use with identical displays arranged in an array, each of which
will process or present that signal with independent timing that can be synchronized across
the array. Contact Christie Support for more details.
•
Switching between sources requires the displays to disconnect, reconnect, and resynchronize.
•
Videowall mode is the default mode and it is used for fast moving/panning video content (for
example; movies, sports, live camera) where frame locking between displays is critical.
Fast Switch Wall Mode
When this mode is enabled, it changes the wall mode from Genlock Wall to Fast Switch Wall.
The primary benefit of this mode is fast switching.
•
The receiver maintains a sync lock using a frame buffer to the display while seamlessly and
quickly switching between sources.
•
Frame rate conversion is available (like the other Fast Switch mode).
•
Use for relatively static content (for example; graphs, text, still images, etc.).
The individual displays are not locked to the source, and latency is a variable. Up to 1 frame of screen
tearing can occur.
•
Fast Switch Wall mode should be used with low refresh, relatively static content.
