What is the model of the TV you are connecting?
Have you done all your Windows updates?'
Have you run the HP Support Assistant ?
Have you run the Windows troubleshooter?

Thank you for your reply and the requested information.
Would you try the following:
- Disconnect the TV
- Start the notebook in safe mode with the power adapter connected and the battery installed.HP PCs - Windows Safe Mode (Windows 10, 8)
- Now make sure the notebook display is set as the primary display
- Once that has been established then try restarting your notebook normally with and without the adapter connected to ensure it is working correctly.
- Once that has been established connect the TV as instructed, setting the TV as a 2nd display.
Please let me know the outcome.
