1. For mounting information, please refer to the Installation Instructions provided by Peerless
AV inside of the boxes of the DS-VW765-LAND mount units.
2. Connect the NEC displays using the included DVI cables and the integrated DVI
loopthrough connections on the bottom of each monitor. Note that the DVI connection
closest to the front of the display is the ‘in’ connection while the connection closest to the
wall is the ‘out’ connection.
The cabling set up below is only one way of completing this. DVI daisy chaining can be
done a number of different ways and still yield the same results. Note that the connections
for each P Series monitor are on the bottom of each display, not the side as shown in the
image below. It may be helpful to start wiring before mounting.
3. Connect the null modem cabling to each display. This should follow a chain that is easy to
remember, like 1-2-3-4 or 1-2-4-3. Note that the null modem cable needed to run from the
source computer to Display 1 is not included in this bundle. This will need to be purchased
separately to control the display remotely over RS232. Looping through the provided IR
cables is optional at this point.

4. Set each monitor ID up individually through the ‘MULTI-DSP’ menu within the OSD. It’s
recommended that the ID’s go from left to right, with the ID No. 1 being in the top left corner.
Note that after the ID’s are set, there are two different ways to communicate to each screen
via the IR Remote. If the setting for the ‘IR Control’ within the ‘MULTI-DSP’ menu is set to
‘Normal’, then the IR remote control cabling is being utilized for communication. In order to
communicate to each screen individually, hold down the ‘Remote ID Set’ button on the
remote control, tap the number of the ID that you want to communicate with, then release
the Remote ID Set button. To test if this was done correctly, press the MENU button and
the OSD should now only appear on the display in which the remote control is
corresponding to. Also, more information on this is located within the User’s Manual.

To communicate to each display over the RS232 connection, make sure that the first display
(monitor ID 1) has its IR control set to ‘Primary’, while all others are set to ‘Secondary’. The
displays should automatically be set to ‘RS232’ for their external control but this should be
checked as well. When all is set, press the ‘Display’ button and the Monitor ID and Target
ID should come up in the left corner of each screen. Use the [+] and [-] buttons on the
remote to change the Target ID to the desired display you wish to communicate with then
press ‘Display’ again. If the menu is then pressed, the OSD menu should appear on the
screen of the desired ID.
5. Use the TileMatrix feature to setup the 2x2 Video Wall. The Tilematrix feature of the NEC
Display allows for one image to be expanded and displayed over a 2x2 Video Wall Setup.
This is accessed through the OSD (On-Screen Display) Controls under the “MULTI-DSP”
main menu icon. Under the TileMatrix sub-menu, enable the feature and set the necessary
parameters that match the 2x2 Video Wall setup. Note that this step will need to be
completed for each screen.
6. Select if TileComp is necessary for this application or not. TileComp works in tandem with
TileMatrix to compensate for the width of the tiled bezels in order to accurately display the
image. Click ‘YES’ on enable to display video wall. Note that this step will need to be
completed for each screen.
