External screen not detected after reboot or startup

[Hans24]

I have connected a LG ISP monitor to my notebook with a HDMI cable. The screen was not detected so I installed the Intel HD Graphics driver. Once this was done the external screen worked perfectly. However, when I shut down or restart the screen is no longer detected. Installing the driver again solves this but hardly seems the right way of fixing this problem. Do Ineed to upgrage other drivers or BIOS ?

@Hans24,

Thank you for posting your query on HP Community,

In this scenario, the best solution would be to update the Bios on your PC either downloading the drivers directly from our HP support website, using this link or download it using HP Support Assistant. 

To download and install HP support assistant on your PC. It should automatically download and install the latest updates and drivers for your PC.

Refer this link to know how to use HP support assistant.

Let me know how it goes for further assistance!

Thank you for the advice but the issue unfortunately remains. I had no recomendded updates but I did upgrade the BIOS to a leter (the last) version. After that I installed the latest Intel HD Graphics driver and the second screen was activated. After a restart however the second screen was no longer detected. I also tried with other Intel HD Graphics drivers (taking the Windows 10 version in account, current version is 1803 and the last driver is for 1809). But it did not work either.

@Hans24,

Thanks for the details,

This could be a problem with corrupt drivers. 

Let's try to uninstall the graphics card drivers from device manager and then do not restart the computer.

Once done, update the drivers from our HP support website, using this link. 

Once done, restart the computer and check if that works.

If the issue persists, I would suggest here is to create a new user account and check if that helps.

Keep me posted on how it goes!

Hi,

I performed the steps as you described, using the info and guidelines from the links.

This did not work...same fenomena: second screen activates after installing the driver, but after restart the second screen is no longer detected. I also tried the Intel Driver Update Utility, but that resulted in the same situation.

Creating a new account in Windows did not work either. Also in that account the second screen is not recognised.

@Hans24,

In this scenario, I would personally suggest you try to perform a system reset on the PC. 

For more details, please follow this link: HP PCs - Resetting Your Computer (Windows 10)

Once done, I would suggest you try to run the Windows update on your PC and check if the issue persists. 

Keep me posted on how it goes!

Thank you 🙂

@Jeet_Singh,

I did the Windows reset without erasing my personal files. This was a bit of work since I had to reinstall the apps and bookmarks, but no problem there. However, the problem is not solved. No difference before or after. I think perhaps the BIOS settings or register settings will have to be changed, but I am not really looking forward at experimenting there...

@Hans24,

As you have tried to perform a system reset and unfortunately nothing has helped to resolve this issue.

In this scenario, before we conclude this to be a hardware issue. I would recommend you try to perform a system recovery either using the partition available on your PC or using the recovery media.

If you have created one soon after purchase of this PC. If you don't have one or for some reason the partition is not working, In that case I would recommend the next option would be to order a set of recovery media. 

To know more about how it works: 

Link 1: HP PCs - Performing an HP System Recovery (Windows 7)

Link 2: HP PCs - Obtaining PC Recovery USB Drives or Discs

If you find it difficult to place an order, you may contact our HP support team to help you order one. 

HP support team can be reached on this link.
