  • PrintPrint
Use the following steps to troubleshoot the webcam on the monitor.

Step 1: Check the USB connection

A USB cable is used to connect a computer to the Webcam and USB ports on the monitor. Check the connection as follows:
  1. Turn off the computer and the monitor.
  2. Unplug the USB cable between the computer and the monitor from both the computer and the monitor.
  3. Turn on the monitor, and then turn on the computer.
    NOTE:After Windows starts, wait at least one minute to make sure that all software that opens with Windows completely loads.
  4. Using the Windows Start button, shut down and turn off the computer.
  5. Connect the USB Type A connector on the USB cable to an open USB 2.0 Type A port on the computer. Connect the USB Type B connector on the USB cable to the only available USB 2.0 Type B port on the monitor.

  6. Turn on the monitor, and then turn on the computer.

Step 2: Check the software settings

Use the following steps to check the webcam software settings.
  1. Make sure the software you are using to view webcam video can use a webcam. For testing purposes, install and use the software that came with the webcam and monitor. If you do not have webcam software, use Windows Live Messenger for testing.
    NOTE:A webcam is not the same as a digital video camera. Many video editing programs do not recognize streaming webcam video. For example, you cannot use Windows Movie Maker to import video directly from a webcam.
  2. In the webcam software settings, select HP Webcam, CyberLink YouCam device, or USB Video Device as the input or source video device.
    For example, in CyberLink YouCam with Windows Vista, select HP Webcam in the Capture Device list under the capture settings.
  3. View the webcam video in the software.
    If video does not display or you are cannot select HP Webcam, the CyberLink YouCam device, or the USB Video Device, continue to the next step.
  4. Unplug all USB devices attached to the monitor. If the device is a mouse or keyboard, temporarily attach the mouse or keyboard to an open USB port on the computer.
  5. Restart the computer, restart the webcam software, and view the webcam video in the software.
    If you can view webcam video, one of the USB devices that was attached to the monitor is conflicting with the webcam. Do not use the device while using the webcam or connect the device to a USB port on the computer.
    If video does not display or you cannot select HP Webcam, the CyberLink YouCam device, or the USB Video Device, continue to the next step.

Step 3: Check Device Manager

  1. Find the webcam in Device Manager using one of the following methods depending on your version of Windows:
    • Windows Vista: click Start . In the Start Search box, type Device Manager. In the Programs list, click Device Manager, and then click Imaging Devices. Under Imaging Devices, find HP Webcam.

    • Windows XP: right-click My Computer and then click Properties. Select the Hardware tab, click the Device Manager button, and then click Imaging Devices. Under Imaging Devices, find USB Video Device.

  2. If HP Webcam (Vista) or USB Video Device (XP) is not listed, use system restore on the computer to go back to a restore point when the webcam was known to work or to a time before the USB cable was connected to the monitor. After a system restore, go back to Step one and check the USB connection.
    If HP Webcam (Vista) or USB Video Device (XP) is listed under Imaging Devices, continue to the next step.

Step 4: Uninstall and reinstall the webcam

  1. In Device Manager under Imaging devices, right-click HP Webcam (Vista) or USB Video Device (XP). Then click Uninstall.

  2. After the device is fully uninstalled, disconnect the USB cable from the monitor and restart the computer.
    NOTE:After Windows starts, wait at least one minute to make sure all software that opens with Windows completely loads.
  3. Disconnect from the Internet if connected.
  4. Remove any external storage devices, including USB devices and discs.
  5. Temporarily disable virus scanning software by right-clicking the icon in the notification area (lower right corner) and selecting Disable, Exit, or a similar command.
  6. Connect the USB Type B connector on the USB cable to the Type B connector on the monitor.
  7. Start the webcam software and view the webcam video.
  8. If video does not display, replace the USB cable with a USB 2.0 cable that has one Type A connector and one Type B connector.
  9. Start the webcam software, view the webcam video and note what happens.
    • If video does not appear, connect the monitor to another computer and repeat these steps. Doing so can help you determine if the webcam hardware is faulty. If the webcam is faulty, service or replace the monitor.
    • If you can view webcam video from another computer, the webcam hardware on the monitor is working. However, the computer requires further troubleshooting or service for USB-related problems.
