The "backend" of the Display is what we call The Event Running Page. At any time you can go to this page by going to the "Dashboard" > Click on the "Active Event" in the list.
Open up the Display Page
At any time you can click on the "View Display" button to open up the live mosaic on a new page. This url can then be put to full screen and cast to an external tv in order to display this live for all your guests to see. If you need further assistance setting up your display to work on the big screen at your event, please contact us with questions!
