Wide Grey Diagonal lines on desktop wallpaper image (see pic) (disappear when desktop is clicked)

[JayUK10]

Any ideas folks? I'm 99% sure it's the monitor because it doesn't happen if I swap monitors. HP support has abandoned me. I sent them pics of the monitor and receipt (as requested) but they haven't been in touch since (despite saying that they would).

That was last week. (Oddly, the wide grey diagonal lines on desktop disappear when desktop is clicked).

Let's make sure if this is a hardware issue, check if the issue persists on the BIOS page.

If the issue persists, this is a hardware issue.

I would personally suggest you contact our HP Support for Out of warranty options.

If not follow the below Instruction.

I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...

HPSA will automatically search for all the latest drivers for your Notebook

1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

   

2. Click Check for updates and messages to scan for new updates.

   

3. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.

4. Click the update name for a description, version number, and file size.

5. Select the box next to any updates you want to install, and then click Download and install.

Also, ensure Windows is up to date.

Select the Start button, and then go to Settings  > Update & security  > Windows Update, and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available
