ScreenBox

ScreenBox is a simple mobile app that helps you turn any screen into a digital sign using your Dropbox account.

With ScreenBox you can display and control videos, pictures, PDF presentations and HTML files automatically across multiple screens. Screenbox supports a wide range of media players like Google Chromecast and Apple TV as well as the major Smart TV brands like Samsung and LG. You can even use it to display content on your PC or Mac. Unlike most digital signage systems, ScreenBox does not require any custom hardware in order to run.
