@AndreBenedict
Thank you for posting on the HP Support Community.

 

I have a few troubleshooting steps we could try to fix the issue:  

  1. Open the onscreen display.

  2. Use the plus (+) and minus (-) buttons to highlight Advanced Menu.

  3. Press the Select button to open the Advanced menu.

  4. Select Factory Reset from the Advanced menu.

  5. Select Yes.

  6. Press the Menu button to close the onscreen display.

    The monitor should show the correct behavior when going into standby mode.

Hope this helps! Keep me posted for further assistance.

Thank you for posting back. 


This sounds like a hardware related issue,

I would request you to reach out to our Support and our Support Engineers should be able to check the available service options in order to diagnose the computer physically. HP Support can be reached by clicking on the following link: www.hp.com/contacthp/
