Have you ever been in a critical client presentation where your Microsoft Teams video freezes mid-sentence, or your screen share turns into a slideshow? You’re not alone—video lag during Teams calls can disrupt collaboration, damage professional credibility, and waste valuable meeting time.
Microsoft Teams video lag problems and their impact
Microsoft Teams video call lag manifests in several ways: frozen video feeds, choppy audio-visual sync, delayed screen sharing, or complete connection drops. These issues stem from network bandwidth limitations, device resource constraints, incorrect Teams settings, or outdated software versions.
We will the most common scenarios causing Teams video lag problems and provides actionable solutions you can implement immediately. We’ll cover network optimization, device configuration adjustments, Teams-specific settings, and troubleshooting techniques for both individual users and IT administrators managing organizational deployments.
Optimize network settings to reduce Teams video sharing lag
Network bandwidth is the primary factor affecting Teams video quality. Microsoft recommends minimum upload/download speeds of 1.2 Mbps for standard video calls and 1.5 Mbps for HD video, but real-world performance often requires higher thresholds.
- Close bandwidth-intensive applications running in the background such as file sync services, streaming platforms, or large downloads that compete for network resources during your Teams calls
- Connect directly to your router using an Ethernet cable instead of Wi-Fi whenever possible, as wired connections provide more stable bandwidth and lower latency than wireless networks
- Disable VPN connections temporarily if your organization permits it, since VPN routing can add significant latency and reduce available bandwidth for real-time video transmission
- Configure Quality of Service (QoS) policies in your router settings to prioritize Teams traffic over other network activities, assigning higher priority to UDP ports 3478-3481 used by Teams media
- Test your network speed using Microsoft’s Network Assessment Tool or third-party services like Speedtest.net to verify you meet minimum requirements before important calls
Adjust Microsoft Teams video settings for better performance
Teams includes built-in video quality controls that balance visual clarity against bandwidth consumption, allowing you to optimize performance based on your specific network conditions.
- Open Teams and click your profile picture in the top-right corner, then select Settings from the dropdown menu to access configuration options
- Navigate to the Devices section and click the “Make a test call” button to verify your camera, microphone, and speakers function correctly before joining actual meetings
- In the same Devices section, reduce video quality by selecting a lower resolution from the camera settings dropdown if you experience persistent lag during calls
- Disable GPU hardware acceleration by going to Settings > General and toggling off “Disable GPU hardware acceleration” if you notice video rendering issues on older devices
- Turn off incoming video during large meetings by clicking the three-dot menu during a call and selecting “Turn off incoming video” to reduce bandwidth consumption
- Enable “Reduce data usage” mode in Settings > Calls to limit video quality automatically when Teams detects network constraints affecting call performance

Update software and drivers to fix Teams video lagging issues
Outdated software versions frequently cause compatibility issues that manifest as video lag, audio desync, or complete connection failures during Microsoft Teams calls.
- Update Microsoft Teams to the latest version by clicking your profile picture, selecting “Check for updates,” and allowing the application to download and install available patches
- Verify your operating system runs the most recent version by opening Windows Update (Windows) or System Preferences > Software Update (macOS) and installing pending updates
- Update your webcam drivers through Device Manager on Windows by right-clicking the camera device, selecting “Update driver,” and choosing “Search automatically for updated driver software”
- Install the latest graphics card drivers from your manufacturer’s website (NVIDIA, AMD, or Intel) since GPU drivers directly impact video encoding and rendering performance
- Restart your computer after completing all updates to ensure changes take effect and clear any temporary system conflicts affecting Teams performance
Configure device resources to prevent my Teams video from lagging
Insufficient system resources cause Teams to struggle with real-time video processing, resulting in choppy playback, delayed screen sharing, and audio-visual synchronization problems.
- Close unnecessary applications before joining Teams calls by opening Task Manager (Ctrl+Shift+Esc on Windows) or Activity Monitor (macOS) and ending processes consuming significant CPU or memory
- Disable background apps in Windows by navigating to Settings > Privacy > Background apps and turning off applications you don’t need running during meetings
- Adjust Teams performance settings by going to Settings > General and enabling “Disable animations” to reduce visual effects that consume processing power
- Reduce the number of visible participants during meetings by switching from Gallery view to Speaker view, which decreases the video streams your device must process simultaneously
- Clear Teams cache by closing the application completely, navigating to %appdata%\Microsoft\Teams (Windows) or ~/Library/Application Support/Microsoft/Teams (macOS), and deleting the contents of the Cache folder
Persistent Microsoft Teams delayed video and connection issues
Despite optimization efforts, some environments present unique challenges requiring advanced troubleshooting techniques to resolve Teams video lag problems effectively.
- Check firewall and proxy configurations to ensure your network allows Teams traffic through required ports and IP ranges listed in Microsoft’s official documentation.
- Test Teams performance on different networks such as mobile hotspot or alternative Wi-Fi to isolate whether the issue originates from your primary network infrastructure
- Monitor Teams connection quality during calls by clicking the three-dot menu, selecting “Call health,” and reviewing real-time metrics for packet loss, jitter, and latency indicators
- Contact your internet service provider if consistent testing reveals bandwidth throttling or routing issues affecting Teams traffic specifically during peak usage hours
- Consider upgrading your hardware if your device consistently shows high CPU usage above 80% during Teams calls, indicating insufficient processing power for video encoding requirements
- Reset Teams completely by uninstalling the application, deleting all local data folders, and performing a fresh installation from the official Microsoft website to eliminate corrupted configuration files
Expert Tip: If you manage multiple users experiencing Teams video lag, deploy network monitoring tools like Microsoft Network Assessment Tool or Wireshark to identify bottlenecks affecting your entire organization rather than troubleshooting individual devices.
