To control a Video Wall it is necessary to switch the Video Wall Processor to Video Wall Mode. This should be done on Video Wall Processor.
Usually Video Walls are controlled from a Video Wall Controller, and the computers the displays are connected to are easily accessible. So it is recommended to set up automatic switching to Video Wall Mode. To do so:
1.Right-click on Video Wall in Resource Tree and choose Video Wall Settings.
2.Click on Launch video wall when Windows starts and click OK. (This option is available for Windows PCs only and is enabled by default.)
To switch to Video Wall Mode, right-click on Video Wall in the Resource Tree and choose Switch to Video Wall Mode and click Close on the dialog window.
Several instances of the Client will be launched. The Client will be switched to Video Wall mode and will become inoperable. At this point it is possible to change settings and control the Video Wall from the Video Wall Controller.
To switch back from Video Wall to standard mode it is necessary to close all Client instances (Alt+F4) and relaunch the Client once more. In this case, operator won't be able to control displays connected to this Video Wall Processor and the corresponding screens will be displayed in the Resource Tree as offline.
