@RodnotRob,

 

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I understand you are in need of support and I'll be glad to assist you.

 

To provide you with an accurate solution, I'll need a few more details:

Have you tried to check if the monitor works on another PC.

Have you tried to swap the cables and check if that helps.

Have you tried to connect another monitor to this laptop.

 

In the meantime, let's try these steps here: 

 

Let's start off by performing a Hard reset on the HP Notebook PCs

Many startup errors and other problems can be resolved by decreasing the amount of power stored in hardware components. Decreasing stored power is sometimes referred to as a "Hard Reset". Use the following steps to perform a hard reset on a computer:

1. If Windows is open, click Start and then Shutdown.

If Windows is not open and the computer has power, press and hold the power button on the computer until the computer shuts off.

2. With the power off, disconnect the power cord from the back of the computer.

3. With the power off and the power cord disconnected, press the power button on the computer for 5 seconds. The power light indicator on or near the power button might turn on briefly but then go out.

4. Reconnect the power cord and turn on the power.

 

 I recommend to restore the BIOS defaults.You could restore the BIOS with this document selecting the reloading the BIOS default settings. That way it will look at the Hardware installed on the Notebook.

Once done, restart the computer and check.

 

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

 

Download and install the troubleshooter from this link.

 

Now try to perform a Windows update:

 

1) In the search box, type and open Windows Updates. 

2) Check for updates. 

3) If the updates are available, click on install and restart the computer.

 

If the issue persists, I would suggest here is to uninstall the display drivers from device manager:

 

Display drivers:

Use shortcut keys Win + X on Windows 10

Select Device Manager.

Expand the entry. Right-click the problematic device and select Uninstall device.

You may need to check the option Delete the driver software for this device, and then click the Uninstall button.

Now restart the computer and then update the Bios, and graphics card drivers from our HP support website, using this link.

 

If the issue persists, I would suggest here is to uninstall the HP Support Assistant from the control panel and then reinstall the latest version.

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.

 

Could you please respond to this post with the details and with the results of the troubleshooting as this will help me in further assisting you.

Eagerly waiting for your response!

that said, If the information I've provided was helpful,

that'll help us and others see that we've got the answers!

Good Luck.
