Why does my LCD have vertical lines?

Asked by asawilliams (368points) February 16th, 2010

I have a Dell 24 LCD and a couple months ago a red vertical line showed up on the right side. It would go away after the monitor was on for a while, but as the weeks passed more lines started to show up and they would go away when the monitor was “warmed up”. Has anyone else heard of this happening?

I’ve got 6 of those on my laptop. Think of your display as a piece of graph paper. There are electrical contacts at the ends of each grid line. Actually, there are 3 apiece, one for red, blue, and green each. If one of the contacts goes bad, you get a line.

Laptop is a Dell, too, about 5 years old. Got a new screen for it last year, and the problem showed up about 6 months ago. Piece of crap. I can get a new screen fo about $150 if I install it myself. Probably not worth it.

Like dead pixels, dead (or in your case, stuck) columns of pixels is a fairly common problem with LCD monitors. Aside from unreliable temporary fixes there might not be anything you can do aside checking if the monitor is still under warranty.

I have not heard of them going away after a monitor warms up though, that sounds strange. Before doing anything drastic I suppose I would diagnose the monitor by auto-adjusting or resetting its internal settings, and trying it out on a different computer if possible (as it could also be the fault of a video card or driver).
