Why is my Windows webcam showing a black screen?

If your Windows webcam is showing a black screen, it's usually due to one of several common issues—ranging from driver problems to software conflicts or even simple privacy settings. It can be frustrating when you're trying to join a meeting or take a quick selfie and nothing shows up. Let's break down what might be going on and how to fix it.

Why is my Windows webcam showing a black screen?

1. Check if the Camera Is Blocked in Privacy Settings

Windows has privacy controls that can prevent apps from accessing your camera without your permission. This is a common reason for a black screen.

  • Go to Settings > Privacy > Camera .
  • Make sure the toggle for "Allow access to the camera on this device" is turned on.
  • Also check the list below to ensure the app you're using (like Zoom, Skype, or the built-in Camera app) is allowed to use the camera.

Sometimes even if the global setting is on, individual apps can be blocked. That's why it's important to double-check both levels.

2. Try Using the Built-In Camera App First

Before jumping into third-party apps, test your camera using the default Camera app in Windows.

  • Press the Start menu , type “Camera”, and open the app.
  • If the camera works here but not in other apps, the problem lies with those specific programs—not your hardware.

If the Camera app also shows a black screen or doesn't open properly:

  • Try closing and reopening it.
  • Restart your computer and try again.
  • Make sure no other app is currently using the camera in the background.

3. Update or Reinstall the Webcam Driver

Outdated or corrupted drivers are another frequent cause of camera issues.

Here's how to update your webcam driver:

  • Press Win X , then click Device Manager .
  • Expand the Cameras or Imaging devices section.
  • Right-click your webcam device and choose Update driver > Search automatically for updated driver software .

If that doesn't help:

  • You can try uninstalling the device (right-click > Uninstall), then restart your PC. Windows will often reinstall the driver automatically.
  • Alternatively, visit your laptop/desktop manufacturer's website and download the latest driver manually.

Some users have found success by disabling and re-enabling the camera device in Device Manager instead of fully uninstalling it.


4. Check for Conflicting Software or Antivirus Blocks

Sometimes, security software or other applications can interfere with camera access.

  • Temporarily disable any antivirus or privacy tools to see if they're blocking the camera.
  • Close background apps that might be using the camera—especially video conferencing tools or background services like Cortana or OneDrive (if they use camera features).

Also, some laptops have physical switches or keyboard shortcuts (like Fn a function key) to disable the webcam. Make sure that's not accidentally enabled.


In most cases, a black screen from your Windows webcam isn't a sign of broken hardware right away. Start with privacy settings and the built-in Camera app, then move on to drivers and background conflicts. Most fixes don't require technical expertise, just a few clicks in the right places.

基本上就這些。
