HP PCs - Troubleshooting HDMI Display and Sound Issues (Windows 10, 8, 7)

This document is for HP PCs with a High-Definition Multimedia Interface (HDMI) connector.
When connecting your computer to an HDMI device, such as a monitor, TV, or surround sound speakers, you might encounter display or sound issues. Use the information in this document to check your settings and to troubleshoot specific problems.

Use the correct HDMI cable for your HDMI device

Most HDTV devices have more than one HDMI input port, therefore it is very important that the HDMI display's input source is set to the same HDMI port that is connected to your computer, for example HDMI 2 to HDMI 2.
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.

Select HDMI sound output as the default audio device

Windows outputs sound to only one device at a time. Select the desired output device by setting the default device. The sound then 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 already been configured, the HDMI output does not display in the sound properties unless an HDMI cable is connected between an HDMI device and the HDMI port on the computer.
Depending on the operating system and the type of sound chip, the images displayed in this document might differ from what you observe when following these instructions on your computer.
Configure the audio output when an HDMI cable is connected. This 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. Right-click the Volume icon on the taskbar, and then select Sounds or Playback Devices.
    Clicking Sounds in the Volume menu
  3. The Sound window opens. On the Playback tab, select Speaker/Headphone or Speakers and Headphones, and then click Set Default.
    Use Default Devices for audio output devices such as headphones or speakers. Use Default Communication Device for making and receiving phone calls.
