Turn on the HDMI port on your HP computer to send both the video and audio from your HP computer to an external TV, monitor or speaker system. While the screen on your computer is sufficient for personal use, you can use an HDMI cable with your computer to display presentations or slideshows for clients on a projector or additional monitor that is suitable for a larger viewing audience. The HDMI port on your HP computer must be activated within the operating system to properly send audio and video to external devices.

1

Turn off the external TV, monitor or projector.

2

Insert one end of the HDMI cable into the "HDMI" port on the side of your computer.

3

Plug the other side of the cable into the "HDMI IN" port on your TV or monitor.

4

Right-click the "Volume" icon on the Windows taskbar, select "Sounds" and choose the "Playback" tab. Click the "Digital Output Device (HDMI)" option and click "Apply" to turn on the audio and video functions for the HDMI port.
