Microsoft Teams display issue when sharing whole display

pjfb · 10-13-2025, 09:37 PM

Running MacOS 15.7.1 - MacBook Air M2
Running dual screens on Dell UD22 and my native display with lid open
Just downgraded from MacOS 26 because performance was just awful
Teams 25255.703.3891.5698.

I have an issue when starting to screen share. When I share a whole screen, one or both external displays switch off and all windows move back to the built-in screen. I've tried uninstalling the client, reinstalling. I have plenty of disk space.

Is anyone else experiencing issues?

Hi pjfb,

Did you try enabling the "Auto-detect video call overlays" option in the Settings tab?

Yes that is already enabled

Hi pjfb

In this case we need to investigate debug data. Would you mind raising a support request?

Hello, I am experiencing the same issue. Were you able to get a resolution?

Hi pjfb and linux50,

I have two additional questions:

How much RAM are your Macs equipped with?
Did you enable "Additional HiDPI modes" in the settings tab? If so, could you disable it?

Regards,
Szymon

Same problem with one of my employees: When share screen in Teams during call its mouse pointer is very laggy.MacBook Pro
MacBook Pro (14-inch, M2 Pro, 2023) Apple M2 Pro
Teams latest version 25306.805.4102.7211
Displaylink driver 14.2.0

macOS Tahoe 26.1
Club3D Dock, 2 screens, 1 LG 27 4K and another second screen HP Full HD

Removing one screen doesn't affect anything
Lag only when sharing. screen in Teams
HiDPI enabled, as tested with Video overlay feature (no difference)

Like to know solution

Hi King Marqy,

"Additional HiDPI modes" option in the settings tab allows scaled modes e.g. 3008x1692 to appear in the mode list. Unless a user intents to use such mode I don't recommend enabling it.

Please, disable "Additional HiDPI modes" and test.

Regards,
Szymon

I’ve experienced similar issues with Teams on Mac when using multiple monitors. One workaround that helped me was setting one external display as the primary monitor in System Preferences before starting the screen share. Sometimes Teams seems to default to the built-in display if no primary display is set. Also, make sure “Displays have separate Spaces” is enabled in Mission Control, it can prevent windows from snapping back to the laptop screen. Hopefully a future Teams update resolves this more permanently.
