A Power View report is always presentable, meaning there is no need to switch to a preview mode to see how your report looks. When using Power View in SharePoint, by default, a report is in design mode. There is also a reading mode in which the ribbon and field list are hidden and the report takes up the whole browser. This is also the case in the full-screen presentation mode (just like a PowerPoint slide show). In both modes, the Filters Area will be visible if it was visible in the design mode.

To switch to either mode, on the HOME tab, choose Reading Mode or Full Screen. To toggle between the views in either mode, use the arrow keys or click on the multi-view icon at the lower left of the screen. You can interact with the report visualizations just like you can in the design mode, but you can't edit the report.
