Troubleshooting HDMI display and sound issues

  • PrintPrint
This document pertains to HP or Compaq Notebook PCs with a High-Definition Multimedia Interface (HDMI) connector.
When connecting your computer to a high-definition multimedia interface (HDMI) device, such as your LCD TV or surround sound speakers, you might encounter certain display or sound issues. Use the information in this document to check your settings and to troubleshoot specific problems.

Using correct HDMI cable for your HDMI device

Most HDTV devices have more than one HDMI input port, therefore it is very important that the TV's input source is set to the same HDMI port that is connected to your computer (i.e., HDMI2 to HDMI2).
If your computer and HDMI device use different cable types, you can purchase adapters. See Overview of HDMI and DVI Connections for PCs for more information.

Setting HDMI sound output

Windows outputs sound to only one device at a time. Select the desired output device by setting the default device and then the sound changes to the correct devices as cables are connected or disconnected. When switching between the sound on the computer and the sound on an external monitor or TV, open the sound devices to ensure the correct output device is selected.
If the device has not been previously configured, when checking the sound properties, the ATI HDMI output does not display unless an HDMI cable is connected between an HDMI device and the HDMI port on the computer.
NOTE:Depending on the operating system installed and the type of sound chip being used, the images displayed in this document might differ from what you observe when following these instructions on your computer.
Use the steps below to configure the audio output when an HDMI cable is connected. Completing these steps allows you to select HDMI as the default when you are using an HDMI connection. When you are not using an HDMI connection, the sound settings default to your computer's speakers and headphones.
  1. Connect the HDMI cable to your computer and to your output device.
  2. Click the Start button, type sound in the Search field, and then select Sound from the list.
    The Sound window opens.
  3. On the Playback tab, select Speakers and Headphones, and then click the Set Default button.

Troubleshooting specific HDMI issues

The following describes some troubleshooting tips you can use when encountering HDMI issues.
A hard or forced reset erases all information in the computer's memory, which might resolve HDMI display and sound issues.
When performing a hard reset, you must disconnect or remove all peripheral devices. You should start and test the computer by itself, and then reconnect one peripheral device at a time. After the devices are reconnected, run HP Support Assistant, or manually install all updated drivers from Microsoft and HP.
Before beginning, turn the computer over and look for a battery compartment door. If there is no battery compartment, use the steps in the sealed or non-removable battery section.

This error sometimes occurs when single mode settings are selected. To resolve the issue, click to accept the message when prompted. The movie will play. For more information on this error and possible solutions, see Content Protection Messages Interrupt Viewing of High Definition Movies
With HDMI, you can view all the actions on both your computer and on your high definition TV screen at the same time. The audio might play, but there might be no video output from the DVD. To correct this issue, update the BIOS and the video drivers to the latest version available for your model.
First, confirm that the computer recognizes HDMI audio by right-clicking the Volume icon in the Windows system tray and selecting Playback Devices. If you do not see the HDMI Output, reinstall or update your audio drivers. Also, make sure the BIOS is up-to-date.
The HDMI port cannot receive audio if the HDMI icon disappears from the sound properties in the Control Panel.
To restore the HDMI icon, follow the steps below.

If the HDMI icon always displays Working status, the audio source is always directed to the HDMI port.
To remove the constant Working status from the HDMI icon, follow the steps below.
  1. Reinsert the HDMI cable into the HDMI port on the computer.
  2. After approximately 10 seconds, switch the audio source in the Control Panel.
    1. Click the Start button, type sound in the Search field, and select Sound from the list.
    2. Select another audio device, click Set Default, and then OK.
The HDMI icon no longer constantly displays Working status and the audio source is no longer always directed to the HDMI port.
If the HDMI icon displays Not Plugged in, audio and video cannot be output to the HDMI port.
To remove Not Plugged in status from the HDMI icon, follow these steps:
  1. Remove the HDMI cable from the HDMI port on the computer.
