The behavior described (very delayed or blank view of a shared screen) matches a low frame-rate screen sharing scenario in Teams.

In Teams, screen sharing is optimized by default for static content (for example, Word or Excel). This default uses a low frame rate so that shared content appears in high resolution. When another user shares content that changes frequently (for example, a video, animation, or rapidly changing screen), this low frame rate can cause the shared view to appear frozen or blank for long periods before updating.

To improve this when the presenter is sharing high‑motion content:

  1. Ask the presenter to enable high‑motion screen sharing while sharing their screen in Teams (desktop client):
    • Start sharing the screen.
    • With the Teams app in focus, press Ctrl+Alt+Shift+T to toggle high‑motion screen sharing on.
  2. If the presenter is on a newer Teams version with the presenter control toolbar, they should use the option to optimize for video when screen sharing instead of the keyboard shortcut.

After high‑motion sharing is enabled, the frame rate increases so the shared screen updates more smoothly and should appear without long delays, though the resolution may drop depending on device capability and bandwidth.

If the issue persists only for some participants, they can check the actual frame rate they are receiving:

  1. In the Teams meeting, open More → Settings → Call health.
  2. Scroll to the Screen Sharing section to see the frame rate and resolution being received.

If frame rate is still very low, the presenter may need to reduce other bandwidth usage or try a wired network connection.
