PowerPoint shows red screen in main presenter view screen

[Midfieldskilz]

Hello,
When using PowerPoint in presenter view mode, the main screen is red yet all the other smaller slides are fine. I have PowerPoint version 13.36 installed. I tried the PowerPoint on my laptop and it works fine which makes me think it's something to do with my iMac. Any ideas would be appreciated. Thank you.

Have you resolved this issue? I'm having the same exact problem and cannot figure out how to fix it. I have searched all over and cannot find much about this issue.

My red screen issue is solved but I really don't know how. I bought a new iMac and backed up my old one. I transferred all data/programs over and the red screen is gone in PP. I really don't understand since with all my other programs the settings remained the same.

I wonder if anyone now has the answer to this issue of a red screen in Powerpoint Present view. I'm using High Sierra 10.13.6 and Powerpoint ms365 so it should be right up to date. So annoying that I can't use Powerpoint on my iMac. Help would be very welcome please...

Even though I am surprised, I shouldn't be how Microsoft locks all threads about this problem. I suffered for a year with this issue as well, but now I finally know the answer:

PowerPoint 2019 (16.3x and above) requires that your GPU support Metal. Once you have Metal support, the red screen disappears and you see the regular preview. How do I know this? I just migrated from a late-2011 MacBook Pro withOUT metal support to a mid-2012 MacBook Pro WITH Metal support. All the other software, including MacOS High Sierra 10.13.6, Microsoft PowerPoint 16.43, etc. is all the same.

It is shameful for Microsoft to dodge this issue and to not fix it. After all, previous incarnations of PowerPoint, like 2011, did not require Metal support in their GPUs to show a preview of the slide projected. It's doubly-shameful that they keep telling users to upgrade to the latest version of PowerPoint or MacOS when that is not the issue at all.
