I want to display two different sites/Urls on a TV Display(Browser Chrome)In case of security reasons, I can not put the content of A for eg in Site B.My approach is now, to open website A with a button 'Start Demo'.Site B is the first and C is the second Website. Both sould run in fullscreen Mode.If I press the button, the should switch Site B and C after 20 seconds. Is there any example out there? Is it better, to view and control the 2 Sites in a popup?Thank you
