  • Datapath Fx4 Wall Controller:
With some of the newest FXServer hardware configurations, one or more wall controllers could be included.
The device we chose for this tutorial is the Datapath Fx4.
  • Datapath Wall Designer software:
The Wall Designer software can be downloaded at:
(If you have an Fx4 unit with an FXServer the software will probably already be installed and the device already configured for your needs)
  • 4 Output devices:
Monitors or projectors supporting 1080p on 60 Hz
(those are needed just to see the final result, the setup can be done also without output devices)

Connect the Fx4 to the Computer for the Setup

Connecting the Fx4 Wall Controller to your computer is very simple:

1. Connect the power cable. (A)

2. Connect a DisplayPort cable to the DisplayPort input of the Fx4 and to the desired output of your graphic card. (B)

We highly recommend using a good quality cable for this connection, a sufficient amount of bandwidth is fundamental for a multi-display configuration.

3. For our installations, we use Club 3D DP 1.4 8k cables.

4. Connect the USB cable to the Fx4 and to your computer. (C)

5. Turn on the Fx4 and the computer. (D)
