Video Wall Using NEC TV Tile Matrix
Note: One downside to doing a tile matrix is that there is no conditioning of the
video signal as it is daisy-chained from TV to TV. Therefore, the signal at the last TV
in the chain (usually the lower-right TV) is a little weaker than the others and
requires minor tuning of the latency settings on the DMP so that the picture is
synchronized with the other TVs.

in the chain (usually the lower-right TV) is a little weaker than the others and
requires minor tuning of the latency settings on the DMP so that the picture is
synchronized with the other TVs.
As an alternative to daisy-chaining from the single DMP, you can achieve the same
result by configuring each of the nine individual DMPs to send the same channel to
each of the nine TVs, and then set the TVs to tile matrix mode. The risk in doing it
this way is that the nine streams must be in perfect synch for the matrix to display
properly.

In the example shown in Figure 30, the TVs are taken out of tile matrix mode and
each DMP is tuned to an appropriate channel. The only requirement here is that you
have one DMP per TV for both control and for the video source.
