I have this pink horizontal line that keeps appearing across my display when logged in my computer, starting up, and even when shutting down. I was playing a computer game(in full screen) and when my computer went into sleep mode the game froze. So, when I force quit out of the program this pink line appeared. Please help, I have no idea how to get rid of it.

Can you give me some suggestions on how to remove this annoying pink line?

although I would use a screen shot to illustrate what I mean, the pink line will not show up on the screen shots for some reason.

Much appreciated,

A quick diagnostic note based on the details in the thread: the pink line not appearing in screenshots is an important clue — screenshots capture the image data the computer is sending, so if a line is visible on the physical screen but not in a captured image it's usually a display or signal-path problem (panel electronics, timing/T‑CON circuitry, or the panel/cable), not something the OS is drawing. This makes the issue more likely to be on the monitor/lcd side than purely a software/rendering bug. (blog.silverpc.hu)

Short, practical checks to do next (safe and quick):

  1. Photograph the line with a phone (for records/warranty).
  2. Show the monitor’s built‑in OSD/menu — if the line is visible over the OSD, that confirms the monitor/panel or internal board is at fault.
  3. Power‑cycle the display (unplug power for ~60s, press/hold power button to discharge) and then retest.
  4. If comfortable and out of warranty, inspect/reseat internal ribbon or T‑CON connectors (laptops and TVs commonly develop ribbon/T‑CON faults that produce horizontal bands).
    Each of those steps is a standard, low‑risk way to narrow whether the problem is the panel, the timing electronics, or the signal path. (smarttvs.org)

Notes on likely causes and caution: intermittent or heat‑related appearance after sleep/resume can point to failing T‑CON circuitry or a panel connection that loses its timing clock when stressed; stubborn, persistent bars usually mean panel/T‑CON hardware needs repair or replacement. Avoid pressing hard on the screen or opening the display if it’s under warranty — panel work often voids warranties and can make things worse. If OSD/photos show the line, prepare your photos and service information before contacting support/repair. (ifixit.com)

This complements earlier suggestions from , and by prioritizing low-risk hardware checks and documentation first (the screenshot/photo test and the OSD test are the fastest way to decide whether the problem is the display itself or elsewhere). If tests point to the panel/T‑CON, repair or replacement is usually the next step. (ifixit.com)

I've had problems with lots of lines..green ones etc and simply changing my resolution did the trick. Look up your graphis card as well and download the latest drivers for it. If its onboard graphics (hope not since you are playing games) just look up the people who made the computer eg. Dell or HP.

If its a card in a pci slot then of course go to the makers of the card for the drivers eg. Nvidia

If all that fails then go next door and borrow your friend's display and plug it into your computer and see what happens. If its a laptop then you are out of luck but there should be a port for an external display somewhere on your laptop. Another option would be to do a system restore to a point where your machine was working fine.

Best of Luck.
