White smudge when the screen is black.

[stevenkucera]

Hello,

I was about to sell an HP Spectre X360, when I noticed a small white horizontal smudge that is visible when the screen is black or a dark colour. It is only faint but would reduce the value and appeal of the product. Can someone tell me why this smear occurs, can it be fixed by screen replacement, and would it be likely to get worse? As far as I know I did not mistreat the product.

I understand you have display issues with your laptop.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Have you tried checking with an external monitor? Does the issue persist?

Does the issue persist in BIOS?

As you mentioned when the display is dark you see a small white horizontal smudge on the display.

If the issue does not persist in BIOS try updating the graphics driver and BIOS on your PC.

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

1.    Turn off the computer and wait five seconds.
