This guide shows you the steps required to set-up a video wall
Video wall daisy chaining (passing video signal from one screen to another) must only be done through DVI loop through and/or Display Port loop through.
Using the 1st screen's HDMI interface as the input source and daisy chaining it via DVI is not recommended as it will create picture issue.
Overview
Some tasks (eg. To set unique monitor id for each screen and SW update) are best done when the screens are not yet mounted and wired up.
It’s best to do the tasks in the following order:
- Update the SW to the latest SW (best done prior to mounting)
- Configure Unique monitor IDs for each screen (best done prior to mounting and wiring)
- Other settings can also be done prior to mounting the screen on the set. (easier). Mount the screens by taking notes of the “Mounting Tips & Requirements”.
- Connect the Video cable, IR cable, RS232 Cable and IR Extender
- Setting up tiling and other configuration if you haven’t done so prior to mounting.
Procedure on how to configure the remote to control specific monitor id is also included.
Update the SW to the latest SW (best done prior to mounting)
To check the current SW on the Screen, press the info button on the remote.
Update the SW if they’re not the latest version (see below)
Refer to the article below
Press [Home]->[General settings]->[Monitor ID]= (Set a unique monitor id)
Note:
Usually numbering start from the top left, to the right, then to the next row, etc.
Setting up Tiling and Other Configuration
Press [Home]->[General settings]->[Eco Mode]= Normal
Press [Home]->[General settings]->[Advance Power Management]= On
Press [Home]->[General settings]->[Pixel Shift]= Off
Press [Home]->[General settings]->[Fan]= Auto/High
Press [Home]->[General settings]->[Switch On State]= Forced On
Press [Home]->[Tiling]->[Enable]= On
Press [Home]->[Tiling]->[H Monitors]= [set according to the number of monitors horizontally]
Press [Home]->[Tiling]->[V Monitors]= [set according to the number of monitors vertically]
Press [Home]->[Tiling]->[Position]= (see example below)
Press [Home]->[Tiling]->[Switch on delay]= Auto
Press [Home]->[Tiling]->[RS232-routing, input]= IR
Press [Home]->[Tiling]->[RS232-routing, IR control]= Normal
Press [Home]->[Tiling]->[Control Monitor-ID]= (set it to unique ID, usually this is the same as the screen position.)
Example:
2x2
Press [Home]->[Tiling]->[Frame comp.]=On (see differences in below picture):

Connecting the Video cable, IR cable, RS232 Cable and IR Extender
Note:
• It is recommended to daisy chain all the cables: RS232, IR, DVI & DP (DisplayPort)
• If the IR Sensor of the 1st screen in the daisy chain is obscured by the setup, please ensure that the IR Sensor Cable is connected to it and positioned in an easy to access location.
• 4K@30Hz can be displayed on the entire video wall (individual screen only support 1080p max) via DP input on the first monitor and DP daisy chain
• DP signal will only be routed via DP daisy chain cables.
If main input is DP, then set DP input on all monitors
• The other option to do daisy chain is DVI
HDMI
It's best to connect HDMI source with HDMI-DVI cable onto the 1st screen.
Alternatively you can use an HDMI splitter and connect each of the splitter's output to each screen.
See diagram below as example of how the screens are to be wired
DVI loop through
Using HDMI Splitter
