3X3 Video Wall in Tile Matrix Mode
TVs used for a video wall must support video wall functionality. The tile matrix
configuration is configured via RS-232 commands, which specify the overall x and y
dimensions of the matrix as well as each TV‟s position in the video wall.
You will need to deploy one DMP per TV with an extra DMP acting as the “video
wall controller.” This N+1 DMP approach is very flexible, allowing the TVs to be
reconfigured in other combinations of video walls with the remaining TVs tuned to
different channels. For example, you can go from a 3 x 3 matrix to a 2 x 2 matrix,
and break out the other five “L-wrap” displays to show different programming. You
can take the TVs out of tile matrix mode and send different programming to each
one using RS-232 commands.

The video inputs on each TV are daisy-chained together using component, DVI, or
HDMI input/output with the video input of the “first” TV (typically the top left TV)
connected to the video output of the video wall controller DMP. For control
purposes, the RS-
HDMI input/output with the video input of the “first” TV (typically the top left TV)
connected to the video output of the video wall controller DMP. For control
purposes, the RS-
232 port on each DMP is connected to the TV‟s RS-232 port.
Each TV receives the same video signal from the video wall controller DMP. Based
on the TV‟s tile matrix configuration, the TV knows to first scale input video to the
size of the configured x,
on the TV‟s tile matrix configuration, the TV knows to first scale input video to the
size of the configured x,
y dimensions, then to display its “piece” of the overall
display based on its configured position within the matrix.
