Hi
For a couple of months I have seen a horizontal pink line appear on my screen, but not all the time.
It is not physical, not a scratch nor a damage to the surface of the screen. It appears for instance when the laptop is booting, when a photo is displayed or when I watch a video.
It does not apply when I browse, email or use my regular office apps like Word, Excel, etc..
So I suspect it may be linked to a graphic card or component that is used only in such cases.
Where do you think it comes from and what can I do to fix this?
Thanks in advance

That's it. Horizontal, pink line at the mid-height of the screen, on the right side.

Hi @GEM ,
Test with HDMI or DisplayPort output.
If the pink line does NOT appear on the external screen → issue is with laptop display panel or its signal path.
If the line appears on both → issue is likely with GPU or GPU drivers.
Open NVIDIA Control Panel → Manage 3D Settings → Global Settings → Set Integrated Graphics as preferred GPU.
Restart and test with videos/photos again.
If the line disappears, this confirms the issue is tied to NVIDIA GPU rendering.
Go to:
Download the latest versions and install cleanly (use Display Driver Uninstaller [DDU] if needed).

Many thanks @Igor28 for offering this diagnosis process.
I tried an external display via HDMI : no problem there. The pink line does not appear on the monitor.
So I tried deactivating the Nvidia graphics via the Nvidia Control Panel to use only the Intel integrated graphics : after rebooting the laptop, the problem is stilll present.
So, according to your reasoning, the issue is with Intel GPU.
So I downloaded the Intel Driver and Support Assistant. It found an update available for the Intel UHD Graphics, so I installed it. After rebooting the laptop, the problem is still present.
So now I understand I need a full install of this new driver, as the update didn't suffice. I downloaded the DDU utility, but it is a bit technical process and I will need to make time for it.
So I'll keep you posted on that clean install but for now I wanted to share the progress I've already made so far.
