What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
To share your screen in Talk Studio, open Share, choose a screen, window, tab, presentation, or media file, then click Show on stream beside that source. Screen sharing is not supported on mobile according to Streamlabs’ guide; Mac users may need to allow their browser to record the screen first.
Share a screen, window, tab, or media file
- Open the Talk Studio browser studio and select Share. The sharing settings are accessed from the up-arrow beside Share; the guide also lists Shift+S as a shortcut.
- Choose what to share: an entire screen, a browser window or tab, slides or images, a presentation, an MP4 video, or background audio in MP3 or WAV format.
- If the source contains sound, enable Share tab audio when offered. Depending on your operating system and selected source, you may instead see an option such as Share System Audio.
- Return to the studio. The chosen source appears in the left panel; click Show on stream beside it to put the content on the audience-facing canvas.
- To make the shared content fill the presentation, use Spotlight (the double-arrow icon) or double-click the window. Streamlabs says the presenter’s microphone can remain audible in this fullscreen layout.
These steps and labels are from Streamlabs’ Talk Studio screen-sharing guide and Talk Studio how-to, both last updated April 25, 2025.
Choose the right source and include its audio
Entire screen
Choose an entire screen when you need to move among apps or show activity beyond one browser window. Before confirming, check that notifications, private tabs, and other sensitive content are not visible.
Window or browser tab
Choose a window or tab to keep the share focused on a particular app or page. For tab sound, check Share tab audio in the sharing prompt. System or tab audio options vary with the operating system and source type, so test the share before the segment you plan to broadcast.

Presentation, video, or background audio
Talk Studio’s native presentation sharing accepts PDF, PPT, and PPTX files. The guide specifies a maximum of 50 MB and 200 pages; large presentations may take time to convert. For a video file, the guide specifies MP4; for background audio, it specifies MP3 or WAV.
Fix permission and compatibility problems
Share controls or screen sources are unavailable
Streamlabs’ current screen-sharing guide says mobile devices do not support screen sharing because of operating-system limitations. Use a computer and browser for this workflow.

Mac does not let the browser capture the screen
On macOS, open System Settings > Privacy & Security > Screen Recording and allow the browser to record the screen. Relaunch the browser if macOS requests it. Streamlabs recommends Chrome in its guest setup guidance; that recommendation is for guests joining a studio, not a complete compatibility list for hosts. See the guest setup guide.
The audience cannot hear the shared content
- Check whether the sharing prompt offers Share tab audio or system audio, and enable the option that matches the source.
- Some operating systems and source types do not offer every audio option. If the control is absent, try sharing a browser tab or another supported source that exposes audio sharing.
- Test audio before going live; a visible share does not by itself mean its audio is being sent.
The share is visible in the studio but not to viewers
Select Show on stream beside the source in the left panel. Selecting a source opens it for the studio; this separate action places it on the broadcast canvas.

When these steps apply
Streamlabs’ screen-sharing, how-to, and guest setup guides were last updated April 25, 2025; its broader Talk Studio getting-started guide was last updated October 1, 2025. Interface labels and operating-system permissions can change, so if a control differs, check the current studio and its help pages. The how-to guide also describes a 1080p screen-sharing entitlement for Pro users and an auto-add option; because plan entitlements and interface options can change, check your current Talk Studio account rather than relying on those details as current.

Talk Studio screen sharing is for presenting a live computer screen or supported media in a Talk Studio broadcast. If instead your goal is to keep uploaded videos looping as a 24/7 YouTube live stream, StreamNeo is a separate cloud service: upload a recording or build a playlist, add your YouTube stream key, and go live. The computer and home connection do not have to stay on. It streams uploaded video, not a live camera feed, and it is for YouTube.
