Damaged pixel screen

Hello everyone, I would like to ask you if you can do something to my screen because the pixels I think are damaged but I did not use any product to damage it. Attached public photo of the current screen. Thanks in advance for the help 🙂

Welcome to HP support community.

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

  

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer: 

I hope that helps.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
