I think the first issue to address is providing the user useful feedback.

The first thing I noticed was that both of my screens were detected correctly, but when I set the option to use them independently it seemed to complete giving no indication of a problem. I'd like to see a clear error message returned when I try to disable cloned mode, and have the UI remain in the original state.

Even better, it should be possible to detected the current virtual size and anticipate the problem. For example, if the user reorients the screens so they are vertically stacked, and the Virtual setting is not tall enough, the "cloned" mode option should become disabled, along with a message indicating the reason and some direction on how to resolve it.

At least then, people aren't left wondering...
