HP PCs - Troubleshooting HDMI Display and Sound Issues (Windows)

This document is for HP computers with an 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 troubleshoot problems.

Step 1: 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.

Step 2: Select HDMI sound output as the default audio device

Select the HDMI device as the default output device. When an external sound device is not connected to the computer, the sound settings revert to your computer's speakers and headphones. When the HDMI device is connected to the computer, the sound settings change to the HDMI device. Open sound settings to ensure the correct output device is selected.
