fine vertical lines throughout display

[spectrefan]

Hi I've had an issue with my display which I can only describe as very faint fuzzy vertical scrolling lines that seem to be present most of the time. Blue and darker colours seem to be affected more than others. When I first got the device the display was crystal clear.

Please find below a photo I've tried to take showing this problem (it seems when uploading some of the quality is lost, look to the right of the blue banner near the text to see an example of the vertical lines which are actually present everywhere).

I've tried the following to resolve the issue/find out what is going on:

start in safe mode

update all of my drivers including bios as per HP support centre

problem is still there whilst charging

changing display setting such as refresh rate and power settings such as panel self refresh and power saving technology

I can also confirm that the lines do NOT appear on an external display device such as a TV when plugged in via HDMI adapter. 

none of these have been effective at all, and I'm not sure what else to try. 

thank you for any help in advancthe blue banner shows the defect as best I can show on a camera photo

Hi @spectrefan,

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 issues with the Vertical Lines on HP Spectre Notebook,

No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution: 

Did you try with an alternate monitor?

Have you tried to boot the computer into the Bios screen and check if the issue persists?

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) 

This would confirm if it's either a hardware failure or an issue with the graphics card drivers so we may reinstall and update the drivers to fix the issue as mentioned above. 

  

If the issue persists on BIOS as well, please try with a TV to identify if it's the LCD or the motherboard/video card failure, 

  

If the issue occurred after an accident (such as dropping it on the floor, liquid spilled on it, etc.) there could be a hardware failure and in such cases, you may need to get the computer repaired via HP (there could be a charge involved if the PC isn't covered by the accidental damage protection plan)
