my camera displays a black screen

Question

my camera is turning black. Half the screen is now black and it is not working right when I turn it on.

Answer 1

I suggest you to update camera drivers to latest version, see if that helps.

Answer 2

Let's check some additional information to help resolve the issue:

1. What is the make and model of your device?

In the search bar, type MSINFO32 and hit Enter.

Please share a screenshot of that window.

2. Press Windows + X and choose Device Manager.

Click View > Show Hidden devices

Expand Camera Section.

Answer 3

Follow these steps to troubleshoot a camera that shows a black or half‑black screen in Windows:

1. Check physical camera and privacy controls
   • Ensure the camera lens is not covered, blocked, or partially obscured (for example by a privacy shutter or slider).
   • If the device has a physical camera switch, button, or keyboard key (often one of the F1–F12 keys with a camera icon, sometimes used with Fn), make sure it is turned on.
   • Clean the camera lens.
2. Test the camera in the Windows Camera app
   1. Open Start > Camera.
   2. Check if the preview works.
      • If the camera works in the Camera app but not in another app, the issue is with that app’s settings.
3. Check app permissions for the camera
   1. Select Start, then Settings > Privacy > Camera.
   2. Under Allow access to the camera on this device, select Change and turn on Camera access for this device if it is off.
   3. Make sure Allow apps to access your camera is turned on.
   4. Under Choose which Microsoft Store apps can access your camera, turn on access for the apps that should use the camera.
   5. If using desktop apps (for example browsers or video conferencing apps), ensure Allow desktop apps to access your camera is turned on.
4. Update the camera driver
   1. Select Start > Device Manager.
   2. Expand Cameras and locate the camera in the list.
   3. Right‑click the camera and select Update driver.
   4. Select Search automatically for drivers so Windows can search online and install the latest driver if available.
   5. Restart the PC after the update completes.
5. Check for Windows updates
   • On Windows 11: Start > Settings > Windows Update > Check for updates.
     • If there are no updates for the camera, select Advanced options > Optional updates and install any camera driver updates, then restart.
   • On Windows 10: Start > Settings > Update & Security > Windows Update > Check for updates.
     • If View optional updates appears, select it and install any camera‑related updates, then restart.

If the screen remains black or half‑black after these steps, the issue may be faulty camera hardware, and testing the camera on another device (for an external camera) can help confirm that.
