HDMI Display and Sound Issues

Step 1: Use the correct HDMI cable for your HDMI device

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

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.
