If you want to use PowerPoint’s Presenter View, or display the presentation through a projector while having slide design view or slide sorter view on your monitor, the computer must support Extended Desktop.

To see if your computer supports extended desktop go to: START >> CONTROL PANEL >> DISPLAYS >> SETTINGS tab. If you have two monitor icons, you should be good to go.

Click on monitor 2 and then activate the┬á“extend my windows desktop onto this monitor.”
