HP Notebook PCs - Troubleshooting HDMI Display and Sound Issues

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.
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.
