Microsoft Teams Black out during Screen Sharing on MSI OLED MPG341CX

Hello @Hassan, Nasrul

Thank you for reaching out and for providing the details of your setup. 

To clarify first: Microsoft Teams does support OLED and high‑refresh‑rate monitors, and the issue you are seeing is not a limitation of the MSI MPG341CX OLED panel itself. When screen sharing appears blank or black in Teams, it is typically related to graphics capture/encoding behavior, display settings (such as HDR), or graphics drivers, rather than the monitor’s refresh rate or OLED technology. 

Based on similar cases, we recommend the following troubleshooting steps, in order: 

1/ Disable HDR on the external monitor 

• If HDR or Auto‑HDR is enabled on the MSI monitor, please turn it off temporarily:  Windows Settings > System > Display > select the MSI monitor > turn HDR off 
• HDR is a common cause of black or blank screen sharing in Teams. 

2/ Update graphics drivers 

• Please ensure your GPU drivers (Intel / NVIDIA / AMD, depending on your system) are fully up to date. A clean driver update often resolves screen capture issues. 

3/ Test with a lower resolution 

• As a quick test, set the external monitor resolution to 1920×1080 during a Teams meeting and try sharing again. Very high resolutions (ultrawide or 4K) can sometimes cause capture failures on certain driver versions. 

4/ Check Teams “Call health” while sharing 

• During a meeting, start sharing the screen, then select More actions (…) > Settings > Call health and review the Screen sharing section. 
• If frame rate or resolution shows as 0 or blank, it confirms a local graphics capture issue rather than a Teams service issue. 

You may find further guidance here:

• Fix screen sharing video display lag issue in Teams 

5/ Try alternative sharing methods 

• Share a specific application window instead of the entire screen 
• If possible, test Teams on the web/browser to help isolate whether the issue is specific to the desktop app 

Please note that lowering the monitor refresh rate (for example, from 240 Hz to 59.97 Hz) is usually not sufficient on its own, as Teams screen sharing is internally limited to a variable frame rate and does not attempt to stream at the monitor’s native refresh rate.  

Note: Please understand that my initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.  

I hope this information is useful. Additionally, as other users have raised similar concerns and may not be aware of where to share their feedback, I hope this response helps clarify the situation and suggests a potential next step. Highlighting this information can make it more visible to others in the community who may be facing the same issue, making it easier for them to find guidance and contribute their feedback as well. 

Thank you again for your time and for raising this important usability concern. If you have any further questions or need additional assistance, please don’t hesitate to reach out. 

I look forward to your thoughts on this.

Teams can work with high‑refresh‑rate and OLED monitors. A black or blank screen during sharing is usually caused by how video is encoded or by GPU/driver issues, not by the panel type itself.

Use these steps to narrow down and mitigate the issue:

1. Check Teams call health while sharing
   During a meeting, start sharing the MSI monitor, then open More → Settings → Call health and scroll to Screen sharing. Verify:
   • Sent frame rate is between 1–30 fps.
   • Sent width/height shows a valid resolution (for example, 1920×1080).
     Exceptionally low or zero values indicate Teams is limiting or failing to send the stream, often due to GPU/driver or bandwidth issues rather than the monitor itself.
2. Optimize for video / high‑motion sharing
   If the shared content is video or animation, enable high‑motion screen sharing:
   • Start sharing the MSI screen.
   • Press Ctrl+Alt+Shift+T (toggle).
     This forces a higher frame rate for the shared content; resolution may drop slightly to accommodate device and bandwidth limits.
3. Reduce GPU load and resolution
   High‑resolution, high‑refresh external displays can stress the GPU and affect Teams encoding:
   • Temporarily lower the MSI monitor resolution to 1920×1080 while in Teams meetings.
   • Close unused apps and browser tabs.
   • Turn off your own video and/or incoming video in Teams to reduce load.
   • If using a dock, try connecting the monitor directly to the laptop’s video port.
4. Toggle GPU hardware acceleration in Teams
   Teams uses hardware acceleration for encoding screen sharing. On some GPUs or drivers this can cause black/blank shares. Try both configurations:
   • In Teams settings, disable GPU hardware acceleration, restart Teams, and test sharing.
   • If already disabled, enable it, restart, and test again.
5. Check for Windows Media Foundation / hardware encoding issues
   Teams relies on Windows Media Foundation for camera and screen‑sharing encoding. On some older or incompatible GPUs, hardware encoding can fail silently and result in black video or black screen sharing. A known workaround is to disable hardware encoding at the OS level so that Windows falls back to software encoding. This is done via a registry change that disables hardware encoding for Media Foundation. After applying that change and restarting, camera and screen sharing start working normally on affected systems.
6. Verify GPU drivers and Windows updates
   • Update the graphics driver from the GPU or laptop vendor.
   • Install the latest Windows updates.
   • Restart and test Teams screen sharing again.
7. Check VDI / protection features (if applicable)
   If using Teams in a virtual desktop (Citrix, AVD, etc.) with screen‑capture protection or app protection enabled, outdated components can cause black screen sharing. Ensure the VDI agent, client, and Teams versions meet the documented minimums; otherwise, users can see a black screen instead of the shared content.

If the issue persists after trying the above, collect a short test meeting where the MSI monitor goes black while sharing and review the Screen sharing metrics in Call health. If frame rate and resolution drop to zero or stay at minimal values, escalate through your support channel with those metrics, GPU model/driver version, and whether hardware acceleration is on or off.
