A Video Wall Server is the computer that hosts the main database of a Video Wall Cluster. It is recommended that only one server be installed in the Video Wall Cluster. Video Wall displays can be connected to this server and it can act as the Video Wall Processor as well. All computers that are part of the Video Wall Cluster (clients and controllers) should be located in the same network.

The Video Wall Processor is the computer that Video Wall displays are connected to. Depending on its configuration it can handle one or several displays. There is not a limit to the number of Video Wall Processors that can be combined in a Video Wall Cluster.

A Video Wall Controller is any computer that can connect to a Video Wall and control it. It can even be a laptop; the only requirement is that the video adapter should support OpenGL > 2.0.

In order to operate Video Wall properly, Nx Witness should be installed on every computer of the Video Wall Cluster:

•Video Wall Server: Full installation.

•Video Wall Processor(s): Client only installation.

•Video Wall Controller(s): Client only installation.

If all Video Wall components are installed on one computer, choose Full installation.
