Detailed Instructions

Restart Microsoft Teams Completely

A simple restart often clears temporary glitches. Make sure Teams is fully closed, not just minimised.

On Windows:

1. Right-click the Teams icon in the system tray (near the clock).
2. Select Quit.
3. Wait ten seconds, then reopen Teams from the Start menu.

On macOS:

1. Click the Teams icon in the menu bar at the top of the screen.
2. Select Quit Microsoft Teams.
3. Wait ten seconds, then reopen Teams from the Applications folder or Dock.

Update Microsoft Teams

Running an outdated version is a leading cause of display issues. Teams updates automatically, but you can force a check.

1. Click the three-dot menu (⋯) next to your profile picture.
2. Select Check for updates.
3. If an update is available, Teams will download and install it automatically.
4. Restart Teams once the update is complete.

Clear the Microsoft Teams Cache

Corrupted cache files frequently cause blank screens. Clearing the cache forces Teams to rebuild its local data.

On Windows:

1. Quit Teams completely (see steps above).
2. Press Win + R to open the Run dialog.
3. Type %appdata%\Microsoft\Teams and press Enter.
4. Select all files and folders inside this directory and delete them.
5. Reopen Teams and sign in again.

On macOS:

1. Quit Teams completely.
2. Open Finder and click Go in the menu bar.
3. Select Go to Folder from the dropdown.
4. Type ~/Library/Application Support/Microsoft/Teams and click Go.
5. Delete the contents of the following folders: Cache, blob_storage, databases, GPUCache, IndexedDB, Local Storage, and tmp.
6. Empty the Trash and reopen Teams.

Disable GPU Hardware Acceleration

Graphics acceleration can conflict with certain drivers or hardware, resulting in blank screens. Disabling it forces Teams to use software rendering instead.

1. Click the three-dot menu (⋯) next to your profile picture.
2. Select Settings.
3. Click General in the left sidebar.
4. Scroll down to the Application section.
5. Toggle on Disable GPU hardware acceleration.
6. Quit and reopen Teams for the change to take effect.

Check Your Webcam and Privacy Settings

If the blank screen appears only when your camera is active, your operating system may be blocking Teams from accessing it.

On Windows:

1. Open Settings > Privacy & security > Camera.
2. Ensure Camera access is turned on.
3. Scroll down and confirm Microsoft Teams is listed under Let apps access your camera with the toggle enabled.

On macOS:

1. Open System Settings > Privacy & Security > Camera.
2. Ensure Microsoft Teams has a tick next to it.

Troubleshooting

If the blank screen persists after completing the steps above, try the following additional solutions.

Test Teams in a Web Browser

Using the web version helps determine whether the issue is with the desktop app or your device.

1. Open Chrome or Edge.
2. Navigate to https://teams.microsoft.com.
3. Sign in and join a test meeting.

If Teams works correctly in the browser, the issue is isolated to the desktop app. Consider reinstalling it.

Reinstall Microsoft Teams

1. Uninstall Teams via Settings > Apps on Windows, or drag the app to the Trash on macOS.
2. Download the latest version from https://www.microsoft.com/en-au/microsoft-teams/download-app.
3. Install and sign in.

Check for Operating System and Driver Updates

Outdated graphics drivers are a common cause of display issues in Teams.

• Windows: Open Settings > Windows Update and install any pending updates. Also check your graphics card manufacturer's website (NVIDIA, AMD, or Intel) for the latest driver.
• macOS: Open System Settings > Software Update and install any available updates.

Disable Conflicting Software

Antivirus programs, VPNs, and firewall settings can occasionally interfere with Teams' rendering. Temporarily disable these tools one at a time to identify the cause.
