PowerPoint Presenter View not showing on extended display when using

In the latest Microsoft 365 of PowerPoint release on Oct 1st'25 , Presenter View fails to display correctly when switching between “Duplicate” and “Extend” display modes.

 

Steps to Reproduce: Connect an external monitor or projector to a Windows laptop.

In Windows display settings, select Duplicate mode.

Open a PowerPoint presentation. Switch to Slide Show mode.

Result : External display only shows the Windows desktop, not the slide show or just duplicates the slideshow.

Presentation runs only on the laptop screen.

Presenter View does not appear.

Option is clicked where it has 'Automatic change to extended mode'

What should happen or atleast it used to be - PowerPoint automatically changes to Extended mode and Presentation shows on the external display. Presenter View (annotations, upcoming slides, notes) appears on the laptop screen.

Build Information: Microsoft 365 -  2509 release cycle  Could you throw some light on this or is it intentionally done ?

    Microsoft have released an update on October 14th which has resolved this issue. Just update your office apps now and it will be fixed

    I've managed to fix it by rolling back to the previous update using the below in an elevated command prompt:

    cd "c:\Program Files\Common Files\microsoft shared\ClickToRun" - hit enter

    officec2rclient.exe /update user updatetoversion=16.0.19127.20240 - hit enter

    This will popup an Office update box - let that run and once completed it should show the previous version in Word etc

    Then disable office updates until Microsoft releases a fix

    Basically before 1st October it didn’t matter whether the computer was duplicating or extending the display, presenter mode would work as you would expect.

    now it only works if the computer is in extended desktop mode before presenting the slideshow.

    this may be an issue with Windows 11 or PowerPoint, I don’t know, but it isn’t working as it did before.

    Hi Viego,

    Thanks for your response. The options you mentioned are already configured. You can verify this issue using the following releases (Current Channel):

    Version 2509 – October 07 Build 19231.20172 .

    Version 2509 – October 01 Build 19231.20156

    Steps to reproduce:

    1. Set the laptop and external monitor to Duplicate mode (press Win + P → select Duplicate).
    2. Run a PowerPoint slideshow in Presenter View. It should display the slides on the monitor and the presenter view on the laptop, but in the above two releases this functionality is broken.
    3. If you start directly in Extended mode, it works correctly. However, when the default is Duplicate mode, PowerPoint should automatically switch Windows to Extended mode, which it currently does not.
    4. It use to work fine before October 1st release.

    Please replicate the scanario and you will see that functionality is broken.

    Regards,

    Hemant Arora
