Display Error - Red and Blue Dots continuously appear on screen

[KaiBarrett]

Hello,

Recently I have been experiencing errors regarding the display on my laptop moitor. I've tried all the usual things - updating graphics and display drivers, and restarting my laptop to no avail. The issue is there are blue and red dots/"thin" lines that appear on my screen - some consistently, others that depend on the page or when/where I move my mouse.

Any help would be appreciated.

Thanks

Hey there! @KaiBarrett, Thanks for stopping by HP forums!

I understand that you have display issue on your laptop.

As you mentioned that after updating driver the issue still persists.

Can you check if the screen in BIOS looks the same?

If yes then it is a hardware issue. Please contact HP for service options.

Also, refer this article to troubleshoot display issues.

Let me know if this helps!

Happy Weekend! 🙂

Hi,

Thank you for your reply.

I looked around in BIOS (but did not modify anything) and the screen looked fine, but bear in mind there was nothing with black colour - something that seems to be affected the most.

Last night I tried one of these tools that flashes random colours but that did not work either, so I am unsure what to do now.

Thanks in advance.

Hi! @KaiBarrett, thanks for the reply.

Thanks for trying out the steps.

As you mentioned that you don't see any dots in BIOS.

Try restoring the BIOS to default and check if that helps.

To restore BIOS tap f9 key in BIOS. Select restore defaults.

Press F10 to save changes and exit.

Also, this looks to be a driver issue please provide the product number of your PC.

I will try to find the best drivers.

Hope to hear from you soon!

Take care! 🙂

Hi,

Thank you for your quick reply!

Unfortunately I'm unable to find out this in BIOS. Nothing seems to happen when I'm pressing F9 when I'm there (please excuse me haha, I'm not that knowledgeable when it comes to that sort of stuff!) Am I in the wrong section perhaps?

Here are my specifications:

HP Stream Notebook PC 11

x64 Based PC

Windows 10 Home

Intel Celeron Processor

Insyde F.07/28/11/2014 (BIOS)

My product number is: L0M39EA#ABU

Thank you!

Hi,

Thank you for your reply.

I have done these steps, but they have not worked unfortunately. Twice to make sure I was selecting the options. Also if it helps earlier in the day I tried to wash the screen with a damp cloth.

Thank you!

Thank you for your reply. What happens if I am out of warranty though?

Thank you for the update,
I appreciate your time and efforts,

If the computer is out of warranty, they could be a charge involved depending on the part being replaced,

Since it's related to the display, you may be asked to send the computer in for a repair at the service center.

You could ask them about the charges and let them know that you've gone through the diagnosis on HP Forums,

That way you wouldn't have to pay for the diagnostics steps via phone and get straight to the part where they tell you about the repair charges.

It's been a pleasure interacting with your and I hope you have a good day ahead.
