If the TVs do support daisy chaining then DMP-1 doubles as the video wall DMP. Its
video signal is switched through to all TVs via the daisy chained inputs. Depending
on the TV model the daisy chain is constructed using component, DVI, HDMI or in
some cases even VGA. This is illustrated in

Tile matrix video wall, with daisy chained video signal
Caveats for TV-based tile matrix video walls:
When daisy chaining the video signal is that there is no conditioning of the video
signal as it is propagated 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 brightness, contrast and color settings on the DMP or the TV so
that the picture is synchronized with the other TVs.

Tile matrix TVs require multiple RS-232 commands to switch them to and from tile
matrix mode. Currently Cisco StadiumVision Director only allows one RS-232
command to be transmitted per event state; hence multiple event states are needed
to switch in and out of tile mode. This means that the switch is not instant, and
spectators will notice the gradual transition.

spectators will notice the gradual transition.
Another transition related caveat is the fact that each TV must change input when
switching to/from tile mode. This results in the TVs going black momentarily and
showing a small on-screen-display that identifies the new input.

DMP-Based Tile Matrix Video Wall
Beginning with Cisco StadiumVision Director Release 2.4, the DMPs have native tile
matrix capabilities. This allows tile matrix video walls to be constructed without
requiring expensive TVs with tile matrix capabilities. DMPs tile matrix behavior is
achieved by stretching the video region in the screen template so it covers 2 or
more TVs in each direction. By adjusting the X,Y coordinates for the origin of the
matrix capabilities. This allows tile matrix video walls to be constructed without
