I purchased a license believing it would allow me to password lock my primary monitor (with windows 10 desktop icons/taskbar) while having my secondary monitor continue displaying a powerpoint slideshow. It seems, however, that the product does not contain this feature. Can someone please confirm or explain?

Thanks for the confirmation. I'm trying to operate the second monitor as a passive kiosk, a large HDTV screen mounted on wall displaying company info in a continuous looping powerpoint slideshow. The primary monitor is in a nearby cubicle, as a private workstation for word, excel, email, etc. The primary needs to be locked on demand/timeout when staff person is away from their desk.

Can DisplayFusion run powerpoint app as a secondary screensaver? Any suggestion of 3rd party utilities that might support what I'm attempting?
