Webcam Showing a Black Screen? How to Fix It (Windows)

Quick answer: A webcam black screen is almost always software, not a broken camera. The usual causes are a closed privacy shutter, another app already using the camera, the wrong camera selected, or an outdated driver. Check the shutter and close other video apps first.

Confirm where the problem is: open the webcam test . If the preview is black there too, the issue is system-wide; if the test works but one app is black, the fix is in that app.

Quick checks first

1. Open the privacy shutter

This is the single most common cause. Many laptops and webcams have a sliding cover or a stick-on shutter — make sure it is open. On a brand-new camera, peel off any protective film, even if it looks clear.

2. Close other apps using the camera

Windows lets only one app use the camera at a time. If the webcam light is on but the screen is black, another program (Zoom, Teams, Discord, OBS, or a leftover browser tab) is holding it. Close them all and restart if needed.

3. Allow camera access

Go to Settings → Privacy & security → Camera. Turn on "Camera access", "Let apps access your camera", and "Let desktop apps access your camera" so the program you are using is permitted.

4. Select the right camera in your app

Apps sometimes default to a virtual or inactive camera. In your app's video settings, open the camera dropdown and pick your actual webcam.

5. Update or reinstall the webcam driver

Press Win + X → Device Manager and expand Cameras. Right-click your webcam and choose Update driver. If that fails, choose Uninstall device, then use "Scan for hardware changes" so Windows reinstalls it.

6. Do a clean boot

If the black screen started recently, a background app may be conflicting. Run msconfig, choose a selective startup with startup items unticked, disable non-Microsoft services, and restart to test.

Why did my camera go black after a Windows update?

Feature updates can replace or break the camera driver, and sometimes reset camera permissions. Reinstall the driver in Device Manager and re-check Privacy & security → Camera, then restart.

Is it the camera or just the app?

Use the webcam test to decide. A black preview everywhere points to permissions, a driver, or hardware — see our guide on a webcam not detected on Windows . A preview that works in the test but not one app is that app's setting; our webcam test walkthrough explains how to confirm it.
