Thanks for the feedback, this topic deserves a tutorial of it's own. You're right, when localhost is enabled the 'Count' value refers to the number of clients. The total number of application windows is the count + one because there is always a master window.
To specify more than one monitor through the Vizconnect GUI for a display:
- Press the 'Visibility' button for the display to open the 'Cluster index and monitor' dialog.
- In the 'fullscreen on monitor(s)' line press the 'specify manually (advanced)' button.
- Enter the list of monitors with brackets, for example [4,3]
