In order for the Dashboard to work, it needs:
The Dashboard displays a single playlist on every monitor you configure for use with the Dashboard. You can configure as many monitors as you would like for use with the Dashboard.
On the Dashboard Screen Manager, a playlist is a list of Web pages the Dashboard displays on a single monitor. A playlist can consist of one single, or multiple Web pages. When a playlist is configured with a single Web page, this single page is refreshed on a user-specified refresh interval. When a playlist is configured with multiple Web pages, the playlist cycles through the pages also on a user-specified interval.
