Windows 10: Red Horizontal Lines ONLY over black videos / screen

Product: HP Pavilion x360 Convertible 14m-dh0xxx

Processor: Intel Core i5-8265U CPU 1.60GHz
Operating System: Microsoft Windows 10 64 Bit


Ever since Windows did an automatic update about a week ago, whenever I watch videos that have dark scenes mainly black, open photos that are black, or restart my laptop with the black HP screen, there's red horizontal lines only in the center of my screen and ONLY in the center of the screen, nowhere else.









I've checked and updated my drivers, including the graphics, and have started it up in BIOS with restarting and pressing F10 but it does not show up there -- it's a white screen, not a dark one.


Does anyone have any suggestions for a solution? The laptop is less than a year old.

horizontal black line on screen

Without you having posted a screenshot of it, it may point to either corrupted graphics drivers or a possible failing hardware part.

We don't know if the horizontal black line is at the top, bottom, middle or where on the screen or the thickness of it or anything else about it.

Hi

the line is fine, straight, black, horizontal, black and about 6cm long. It is situated 3cm from the bottom of the screen, and just to the right of centre. I have tried to take a screen shot of it but when I paste to Word it does not appear on the image.

 

Black line (horizontal) on the screen

Thanks for replying, actually the problem is a black single horizontal line, not a black screen.
