Display PowerPoint/Google Slides in whole screen when casting from MacBook Pro

In this article, we will show you if you try to present your MacBook Pro to AeriCast Add-on app via OptiSigns app. There is an extra black space on your screen. It is because the MacBook Pro is 16:10 in resolution. Most TV screens are 16:9.

Here is the suggestion:

1. Upload the PowerPoint file to Microsoft 365 or Google Slides. Open the file in Microsoft365/Google Slides in the web browser.
   
   Go to https://present.aericast.com and present the specific browser "tab" of the M 365/Google Slides page, instead of the whole screen.
   
   Then resize the browser window to fit the presentation slide content, assuming it's 16:9 based.
   
   This will cast the presentation to the entire TV screen without additional blank spaces.

2. Change the MacBook Pro's resolution to a 16:9 resolution during the presentation, but this may require a 3rd party app to do so → This is Apple's limitation.
