Hi @tomass83,


Good Day. Thank you for posting your query in the HP community.  I reviewed the post regarding HDMI issues with the computer. Fabulous description and excellent troubleshooting were done by you. Great job! Kudos to you on that score. 🙂


For me to assist you with accurate information I would require more information regarding this.

  • Did you connect it to an external TV to check if it works?
  • Did you try multiple HDMI cables?
  • Has it ever worked before?
  • Please let me know the complete model# of the computer to assist you better.

For now please try these steps:

Please try with a different HDMI cable and connect it to your TV.

  • Right-Click on start button> click device manager> expand display adapters>then select the display drivers that are listed and right-click on it and uninstall the drivers.
  • Check the box that states delete the software for this device.
  • Then restart the computer and update the bios chipset and graphic drivers from this link: Please select the country and type the product# of the computer. Then follow the on-screen instructions to update it.(if the drivers are available. Otherwise, proceed to the next step)

If it still does not fix the issue, please perform the relevant steps for HDMI related issues from this link: regarding video issues. If there is no hardware issue with the computer, this should do the trick for you.


Please perform all these steps patiently as it is critical to resolving the issue. The trick is to remain patient, Going by your technical expertise and competence I am sure you will be able to perform these steps without breaking a sweat. 🙂


Let me know how it goes and you have a great day!
