Hi @PauliHayman,

Thank you for showing your interest in HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for the First Time Here? Learn How to Post and More.

As I understand you are having Blue vertical lines on your HP Envy 27. Don't worry as I have a few suggestions to help you resolve this issue.

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

What is the product number of your product? Use this link to find it: http://support.hp.com/us-en/document/c03754824 

Did you check for any damage on the PC?

Have you tried to update the drivers?

Have you checked if the issue persists even in the Bios screen?

In the meantime, let's start off by performing a Hard reset on the Notebook:

Step 1: Performing a hard reset

Resetting the computer can resolve many issues that cause a blank screen. Use the steps in Performin...

Step 2: Connecting an external monitor to test the display

The notebook screen display might remain black when there is a corrupted graphics driver or a problem with the LCD display backlight. To test the display, attach an external monitor and restart the computer. Testing with an external display is helpful if the notebook display is black but you can hear sounds; such as fans, spinning drives, or beep tones that indicate the computer is operating.

Step 3: ​​​​Boot the computer into the Bios screen and check if the screen has vertical line.

1. Turn off your computer
2. Make sure you have connected the power cable
3. Turn on your notebook, as it is starting press the  F10 button repeatedly

Once you are in the BIOS, if the screen has vertical line, it is likely a hardware failure. The next two steps may resolve the issue. The first one is to do a hard reset. I have included the document 'Performing a Hard Reset or Forced Reset'. The next and final step is to perform a BIOS update. I have included the information here for you 'Updating the BIOS' as well as updating the graphics card drivers from our HP Support website, using this link.

For more assistance, please review and follow the steps set out in the HP Support document: Display Quality Issues. I think you want to focus your attention on the section Solid horizontal or vertical red, green, or blue line.

Please respond to this post with the details and the result of the troubleshooting for further assistance. 

Eagerly waiting for your response!

I hope you have a good day ahead,
