When screen sharing on some Mac devices the screen share is showing smaller in the studio and not taking up the entire media player window in the auditorium.

I've tested this on 3 devices, 2 Macs and 1 windows. Screenshots attached show how the screen share was displayed in the auditorium for each using the same slide deck on each device.

Mac 1 - Sharing slides in Keynote, Entire Screen view using Google Chrome.

Mac 2 - Sharing slides in PowerPoint, Window view using Firefox.

Windows - Sharing slides in PowerPoint, Window view using Google Chrome.
