Try to uninstall or reinstall video driver,. try to go to the bios of your omputer and check if the lining is still there, if it is, then its either your video card or lcd thats having a problem. try to attach an external monitor to your computer, if external monitor looks fine. lcd is the problem.

This is most likely a sign of a failing mainboard or a video adapter. On some cases it may be a issue with just the display.

If the lines dissapear when the display is moved open or closed the issue could be the cables between the lcd display and the mainboard.

Unless its a cable problem this repair won't be cheap. I'd recommend you get a professional to look at the laptop to confirm the fault, if you are in warranty send it to acer repair.

Horizontal and vertical lines on ACER laptop


Hi there some how your laptop screen pressed & the screen is damaged. Just the option is replacing the screen. Another reason is over heating of screen by manufacturing default. Your laptop still under warranty so i suggest you visit the Acer service center & claim the damaged things if your screen does not have any over pressed symptom then. I hope you understand me. Thanks & waiting for your feedback.

3 year old HP laptop. First screen with diagonal


Hi:
I am not 100% sure, but you could have a problem with the onboard video on your laptop. If you hook up an external monitor to your laptop, and boot to the external screen, this will tell you if your laptop screen is ok, if the video displays the same on a external monitor. To get to the external display, some laptops require that you toggle to them, such as holding down the function key and hitting F8, but your model may differ.

Screen lines on MacBook.


Sounds like dropped pixels.  My first guess is the computer has been dropped on its corner, with the pixel dropout radiating diagonally from the corner.
My saint bernard sat on my g3 lombard, and I have vertical pixel dropout because of it, from the top of the screen to the bottom.
And no, it is not normal for a macbook to have lines across the screen.
