Introduction

The aim of this configuration setup guide is to provide you with the basic knowledge of our x4 software 

functionality and explain how to setup and program your video wall.
The Datapath x4 is a multi-display controller allowing customers to arbitrarily scale, rotate and crop their 

input content to each of the four outputs.

The x4 is a very flexible display controller and not all possible configurations can be documented within 

this setup guide, however the principles are the same for all configurations.
The x4 is designed  to capture areas of the source canvas (video) and display those areas on the display 

 

monitors,  a good example of this can be seen in Fig.5 on page 9.  The green area is the source canvas and 

the yellow areas depict the monitor configuration, covering the area of the source to be captured.
Throughout this setup guide the source video is referred to as standard wide screen resolution of 1920  

 

horizontal pixels x 1080 lines.  If your video source is different from 1920 x 1080 then substitute the figures 

accordingly.
The measurements given in this guide for the monitors are an example only and should substituted with 

the dimensions of the actual monitors in use.

 Equipment Required 

•  A set up PC  with the x4 application installed (this can be the source of the video)
•  Calculator
•  Tape measure
• 

Monitor manufacturer’s line drawing. (Optional) 

General Setup

Ensure your monitors are in place and fastened securely.  Connect all four screens to the x4 DVI-I output 

connectors on the rear of the x4 (see x4 User Manual).

When configuring the x4, you must ensure that the x4 unit is powered and that the USB cable is 

 

connected. Ideally the input should be connected so the cropping and scaling settings are associated with 

the correct input canvas resolution.  With no signal connected, the canvas size is assumed to be the 

 

preferred  mode that has been programmed into the input EDID. 
Connect the setup PC to the x4 using the USB cable provided and open the x4 application .
