Connecting multiple displays to one player
Multiple displays may be connected to a single media player/computer two different ways, using
Video Over Ethernet or using Tile Mode with VGA or DisplayPort video inputs.
Connecting multiple displays with Video Over Ethernet (VOE)
To connect multiple displays to a single media player/computer, each display must be connected to
the same sub-network as the media player/computer. The input source of each display must be set to
VOE. With VOE, displays are connected to media players/computer by establishing an association
between the media player/computer and one or more displays on the network with the VOE software
that runs in the media player/computer. Up to 4 displays may be associated with a single media
player/computer (See the VOE Users Guide provided with the display for more detail). When multiple
displays are associated with a single media player/computer, the displays may be mirrored (a single
desktop image displays on all the displays simultaneously).
The image may be extended across all the displays simultaneously using the View Span “Display
Resolution” dialog box.
The displays may be treated by an application as though there were up to 4 individual displays
connected to 4 graphic adaptor heads on the media player/computer.
The association of up to 4 displays is the technical limit, and depending upon the complexity of the
desktop image to be displayed (playing flash, or streaming video), the number of displays which can
be associated with acceptable video performance may be less than 4 (See the Video Over Ethernet
User Guide for more detail).
Connecting multiple displays with Tile Mode
The recommended cable routing for daisy chain in Tile Mode is to start with the upper left display and
connect across the upper tier of displays going from left to right to the last display in that tier. Then
cable from the upper right display to the display just below it and connect across from right to left to
the last display on the left. Continue this back and forth, top to bottom cable route for all the tiers in
the wall as indicated in the next figure.
