My guess is a video driver problem, either an old one or a setting within PowerPoint ...

First, I'd try looking to see if there is a newer video driver available from the computer manufacturer.

Then go into PowerPoint, File>Options>Advanced ... go to the Display section, and tick the box for Disable Slide Show hardware graphics acceleration and OK your way out.

That may solve the diagonal "mirror" image problem.

As I was reading through the topic, I was thinking it's a video problem as you were. I am swaying more to the aspect ratio setting for the video, than the driver. I would check the Win 10 settings to system video and make sure no one has increased the "scale and layout" for text, apps and other items. I would also check to make sure the resolution is set to the recommended setting as well as the proper orientation.

Excellent news!  I'm so glad winchester73's suggestion solved the problem and saved the school a computer. 

(With the Sysnative Forum migration over the weekend from vBulletin to XenForo forum software, there are still custom settings to be made.  The custom smilies are a low priority.)

Yes, it's indeed excellent news!

Winchester, what that option exactly mean? And why on other computers it's not necessary to chose this option?

(Corrine, yes, I like the "new" Sysnative. I will find the happy dance icon somewhere else. :)  )

Learned something new too! I knew there was a "Disable hardware graphics acceleration" option in PPT. I even knew if you changed that setting in PPT, it automatically changed that same setting in Excel and Word too (at least that's how it works in Office 2016).

But what I didn't know was there is a separate disable hardware graphics acceleration setting specifically for "Slide Show"!

My guess (and to address DR M's question) as to why this is a separate setting is PPT presentations are often fed through a variety of video hardware via docking stations, large screen displays or directly to "projectors". Disabling this might help with possible compatibility issues.

Still not sure why this particular computer, and only that computer was affected. It might be interesting to know how it is used.

Anyway, always good to give "those little grey cells" something new to do. :)

Glad it turned out to be something simple.  Lots of variables ... perhaps the computers had different versions of Windows 10, or PowerPoint, or the video configuration on a computer was incompatible with the Office feature set ... could be a lot of things.

Office 2013 and above rely on hardware acceleration, which is managed through the operating system, which relies on up-to-date and compatible display drivers.  It works fine, unless it doesn't  ;)

The important thing is that it worked. I didn't even mentioned the driver update, as I was talking on the phone and she wouldn't understand. Just provided that option.

Thank you very very much, once more.  :)
