Firstly ensure the appropriate user group has monitor wall access in the VMM
In the SSM Client Console open the VM menu:
You may need to select the virtual monitor wall, that has been configured in the VMM
Click on the Stop button:
This will hand monitor wall control over to the client
You can then change the layout to a different split:
Or assign a layout to the monitor wall by clicking and dragging over the layout to the monitor wall representation menu
To see what cameras on are on the current layout, click on this button
The cameras will then be displayed on a layout on the right of the VM menu. If you need to control the PTZ on the monitor wall, you can do so from this layout
