I know I can run a single client that spans all 3 displays, but that creates complications on the development side for screen management. Do you know if there is any restriction on having three client applications running on one PC, one per display? If so, how?
I think you can have Runtime Viewer on one screen, Secure Viewer on one screen and Web thin client on one screen. But keep in mind the high CPU usage this is going to cause. So total 2 thin clients with one runtime license.
