Kasper de Jonge shows how you can make Power BI report pages automatically rotate:
This question comes up pretty regularly, I have a big screen in my hallway and I want to show some Power BI reports that rotate. Now there is some build in functionality in the Windows 10 App for Power BI for it that you can check out here. But there have been some cases where this doesn’t work, like for example if you want your report to run outside of your domain using B2B or when using Power BI embedded that both cannot load the report in the Win 10 app.
For those cases, Kasper has a solution involving an external Chrome add-on.
