If you have Presenter View on monitor 1 and slide show on monitor 2, you can now clone the slide show to monitors 3 and 4 to have the same slide show display on 3 monitors.

The Settings button shows the settings dialog box that allows you to setup automatic cloning of windows of applications. After setting it up, all existing and new windows of selected applications will be automatically cloned to the chosen displays.
