To share your screen in Talk Studio, select Share, choose a screen, window, tab, presentation, or supported media file, then click Show on stream beside that source. Mobile screen sharing is not supported in Streamlabs’ current guide. On a Mac, you may first need to grant the browser Screen Recording permission and relaunch it.
Share a screen, window, or tab
-
Open the Talk Studio browser studio and select Share. The up-arrow beside Share opens sharing settings; the guide also lists Shift+S as a shortcut.
-
Choose what to share: an entire screen, a browser window, or a browser tab. Select only the screen or window you intend viewers to see; an entire-screen share can expose other open apps and notifications.
-
If the source contains sound, enable Share tab audio or choose system audio where that option is offered. Audio options depend on the operating system and the selected source.

Video and background audio
The how-to guide lists MP4 for video and MP3 or WAV for background audio. Choose the relevant media source in Share, then use Show on stream to put it on the canvas. If the material has sound, verify the audio option and test playback before the live segment.
Make shared content easier to see
Use Spotlight (the double-arrow icon) or double-click the shared window to emphasize it in a fullscreen layout. Streamlabs says the presenter’s microphone can remain audible while the shared content is fullscreen. Check the preview before continuing so the intended content, rather than another window, is prominent.

Troubleshooting screen sharing
| What happens | What to check |
|---|---|
| Screen capture is unavailable on a Mac | Grant the browser permission under System Settings > Privacy & Security > Screen Recording, relaunch if prompted, and retry. |
| The source is selected but viewers cannot see it | In the studio’s left panel, click Show on stream beside the source. |
| Viewers cannot hear the shared tab or media | Enable Share tab audio or the available system-audio option. If no audio option appears, it may not be supported for that OS and source combination; test another supported source. |
| The presentation is not ready | Confirm it is a PDF, PPT, or PPTX within the guide’s stated 50 MB and 200-page limits, and allow time for conversion. |
| You are trying to share from a phone or tablet | The official screen-sharing guide says mobile screen sharing is unsupported. Join from a computer to present a screen. |
| The shared content is too small to follow | Use Spotlight or double-click the shared window to emphasize it, then confirm the layout in the preview. |
