Microsoft Teams Camera Showing a Black Screen? Here's the Fix
Updated: Sep 27
You join a Teams meeting, click the camera button, and all you see is a black box. The camera is selected, there's no error message, and nobody can see you.
In a recent case I worked on, the webcam showed up in Teams under Settings > Devices, but the preview stayed black. The camera hardware was fine. The problem was how Windows and Teams were accessing it. Here's how I track this down, starting with the quickest checks.
The Symptom
In Teams, go to Settings > Devices (in the new Teams, Settings > Devices > Camera). The camera is listed correctly, but the preview window stays black, like this:
Fix 1: Check the Camera Shutter and Keyboard Key
It sounds obvious, but it's the most common cause I see. Many laptops and monitor webcams have a small sliding privacy shutter over the lens. Some laptops also have a camera on/off key (often one of the F keys with a camera icon). Make sure the shutter is open and the camera is turned on.
Fix 2: Close Other Apps Using the Camera
Only one app can use the camera at a time on many systems. Close Zoom, Webex, OBS, the Windows Camera app and any browser tabs that might be using it, then check the preview in Teams again.
Fix 3: Check Windows Camera Permissions
Open Settings > Privacy & security > Camera.
Make sure Camera access and Let apps access your camera are on.
Make sure Microsoft Teams is turned on in the list. For older versions of Teams, also turn on Let desktop apps access your camera.
Fix 4: Test the Camera Outside Teams
Open the Windows Camera app. If the picture is black there too, the problem is the camera or its driver, not Teams. If it works in the Camera app, the problem is Teams. You can also test by joining a meeting at teams.microsoft.com in your browser.
Under the preview in Teams, Open camera settings takes you to the Windows camera settings, where you can check the camera and turn it off and back on.
Fix 5: Restart Teams and Clear Its Cache
Fully quit Teams by right-clicking its icon in the system tray and choosing Quit, then open it again. If that doesn't help, reset Teams to clear its cache:
Go to Settings > Apps > Installed apps.
Find Microsoft Teams, click the three dots, then Advanced options.
Click Reset. You'll need to sign in to Teams again afterwards.
Fix 6: Update or Reinstall the Webcam Driver
Right-click Start and open Device Manager.
Expand Cameras (or Imaging devices), right-click your webcam and choose Update driver.
If that doesn't help, choose Uninstall device, unplug and reconnect the camera (or restart for a built-in one) so Windows reinstalls it.
For external USB cameras, try a different USB port, and plug directly into the computer instead of a hub.
Fix 7: Don't Forget Monitor Webcams
If your webcam is built into your monitor, the issue may not be Teams at all. Many monitors with built-in cameras, like Dell's conferencing displays, rely on the manufacturer's drivers and firmware. Windows can detect the camera, and Teams can see it, but an outdated driver still gives you a black preview.
Find your monitor's model number.
Go to the manufacturer's support website.
Download and install the latest webcam driver, monitor driver and any firmware update.
Restart the computer and test the camera in Teams again.
In the example above, Teams detects the DELL Display 4MP Webcam, but the preview stays black. Updating the monitor's webcam driver and firmware is often what fixes integrated display cameras.
Fix 8: Check Your Antivirus
Some antivirus and security suites include webcam protection that blocks apps from using the camera. If you have one, check its privacy or webcam settings and allow Microsoft Teams.
Still Stuck?
A black camera in Teams rarely means the camera is broken. It's usually a permission, another app, or an outdated driver. If you've worked through these steps and it still won't show video, IT-Tech can connect remotely and get your camera working before your next meeting.
