Advanced HDMI display and sound troubleshooting for Windows

Use these advanced troubleshooting procedures for issues with HDMI display and sound.

Performing a hard reset

A hard or forced reset erases all information in the computer memory, which might resolve HDMI display and sound issues.

When performing a hard reset, you must disconnect or remove all peripheral devices. Test the computer by itself, and then reconnect one peripheral device at a time.

Update the PC with HP Support Assistant

Use HP Support Assistant to find and install updates, including BIOS updates, for your computer with Windows.

  1. In Windows, search for and open HP Support Assistant, or click the app icon in the taskbar.

    If the app is not installed on your computer, download the latest version from the HP Support Assistant website.

  2. On the My Dashboard tab, find your computer, and then click Updates.

  3. Wait while HP Support Assistant analyzes the system.

  4. After the analysis completes, select the listed updates, download and install the updates, and then follow any on-screen instructions.

  5. If prompted, restart the computer, and then close the tool.

Installing computer updates using Windows Update

Find and install updates for your computer with Windows 10.

  1. In Windows, search for and open Windows Update settings.

  2. Click Check for updates.

    If there are any available updates, they begin installing automatically.

  3. After the updates install, restart your computer, if necessary.
