Hi @damblymotors,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having display quality issues on your HP notebook. Don't worry as I have a few suggestions which should help you resolve this issue.

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

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 green dotted lines.

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 dotted lines, 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.

If the issue is diagnosed, I would personally suggest you contact our HP phone support for available service related options. If your product is out of warranty, please choose paid options to get the tech support number.

(2) Next, choose the 'Contact Support' tab at the top and scroll down to the bottom of the 'HP Support- Contact' page to fill out the form provided with your contact information.

(3) Once completed click the 'Show Options' icon on the bottom right.

(4) Lastly, scroll down to the bottom of the page and select 'Get the phone number.' A case number and phone number will now populate for you.
