Instructions

  1. 1

    Backup any important or critical files prior to troubleshooting the HDMI connection.

  2. 2

    Navigate to the "Start" menu, "All Programs" and "Windows Update" to launch the Windows Update utility. Scan for new updates and install any hardware device driver updates that are available for the HDMI board. Restart the computer and check the HDMI connection to verify whether the problem has been resolved.

  3. 3

    Navigate to the "Start" menu, select the "Control Panel" and then click "Small Icons" from the "View by" dialogue box. Click "Device Manager" and click the triangle next to the entry for "Display Adapters." Right-click on the name of the display adaptor and select "Update Driver Software" from the context menu. Click "Search Automatically for Updated Software" and allow Device Manager to install the updated device driver if one is found. Restart the computer and check the HDMI connection to verify whether the problem has been resolved.

  4. 4

    Power off the computer system and remove the power cord from the back of the computer and the HDMI cable from the video card. Attach the anti-static wrist strap to the case and connect the other end to either arm. Remove the cover and remove the single screw that holds the HDMI board in place. Pull straight up on the HDMI board and remove it from the system, releasing any small plastic catch that may be holding it in place on some motherboards. Immediately replace the HDMI board right back into the same slot it came out of. Insert the retaining screw and reconnect the HDMI cable and power cord. Restart the computer and check the HDMI connection to verify whether the problem has been resolved.

Tips and warnings

  • Check the connection on each end of the HDMI cable and make sure that the video display that the HDMI cable is plugged into is set to receive video on the same input that is being used.
  • Never work inside a computer without proper static protection or when the power is on.
