Microsoft Teams is a popular platform for online meetings and collaboration. However, some Windows 11 users encounter a green screen issue during video calls. This problem can disrupt your meetings and make video sharing impossible.

Fortunately, fixing the green screen issue is usually straightforward. This guide will walk you through simple, step-by-step solutions to get your Teams video working properly again.

Each step explains why it matters and how to perform it, even if you’re not very tech-savvy. By following these instructions, you can quickly resolve the problem and enjoy smooth video calls.

Let’s begin with some quick checks before moving on to detailed troubleshooting.

Quick Note: Prerequisites and Initial Checks

• Check Your Camera: Make sure your webcam is properly connected and working with other apps like the Camera app or Zoom.
• Update Microsoft Teams: Running the latest version ensures you have all the recent bug fixes.
• Windows 11 Updates: Keep your system updated to avoid compatibility problems.
• Close Other Apps Using the Camera: Sometimes, other apps may block Teams from accessing the webcam.

Step 1: Restart Microsoft Teams

Sometimes, a simple restart fixes temporary glitches. Close Microsoft Teams completely, then reopen it.

How to do this:

1. Click the X button on the Teams window or right-click the Teams icon in the taskbar and choose Close window.
2. Press Ctrl + Shift + Esc to open Task Manager.
3. Look for any Teams processes under the Processes tab. If found, select them and click End task.
4. Open Microsoft Teams again from the Start menu or desktop shortcut.

This step clears any temporary issues that may cause the green screen.

Step 2: Check Camera Permissions in Windows 11

Microsoft Teams needs permission to use your camera. If permissions are disabled, your video may show a green screen or no image at all.

How to check permissions:

1. Press Windows + I to open Settings.
2. Go to Privacy & security > Camera.
3. Make sure the toggle for Camera access is turned On.
4. Scroll down and ensure Let apps access your camera is also On.
5. Find Microsoft Teams in the app list and verify its toggle is enabled.

Allowing camera access ensures Teams can properly display your video feed.

Step 3: Disable Hardware Acceleration in Teams

Hardware acceleration uses your computer’s GPU to improve performance, but it can sometimes cause display issues like a green screen.

To disable hardware acceleration:

1. Open Microsoft Teams.
2. Click your profile picture in the top-right corner and select Settings.
3. Go to the General tab.
4. Look for Disable hardware acceleration and check this box.
5. Restart Teams to apply the change.

Disabling this option forces Teams to use software rendering, which can resolve video problems caused by GPU conflicts.

Step 4: Update Your Graphics Drivers

Outdated or corrupted graphics drivers can cause video display issues, including the green screen in Teams. Keeping your drivers updated is vital for proper video functioning.

How to update your graphics drivers:

1. Press Windows + X and select Device Manager.
2. Expand the Display adapters section.
3. Right-click your graphics card and choose Update driver.
4. Select Search automatically for drivers.
5. Follow any on-screen instructions to complete the update.

If Windows doesn’t find updates, you can visit the manufacturer’s website (like NVIDIA, AMD, or Intel) to download the latest drivers manually.

Step 5: Clear the Microsoft Teams Cache

Teams stores temporary files that might become corrupted and cause display issues. Clearing the cache can fix these problems.

To clear the cache:

1. Close Microsoft Teams completely.
2. Press Windows + R to open the Run dialog.
3. Type %appdata%MicrosoftTeams and press Enter.
4. Delete all files and folders inside this directory.
5. Restart Teams and check if the issue is resolved.

This step removes corrupted temporary files that may interfere with video rendering.

Alternative Method: Use the Web Version of Microsoft Teams

If the desktop app still shows a green screen, try using the web version of Teams as a temporary workaround.

• Open your preferred browser (like Edge, Chrome, or Firefox).
• Go to https://teams.microsoft.com.
• Sign in with your Microsoft account and join your meetings.

The web version uses your browser’s video handling, which may bypass issues present in the desktop app.
