Recently a thin black horizontal line appeared across my computer screen. At first it was there for a while then went away, now it seems to be permanently there. Anyone know why it is there or how to get get rid of it.

Do you happen to have a Trinitron monitor? Sony's monitors have two very thin lines that are shadows that get projected on the screen. They are shadows of the stabilizing wires the monitor has. I noticed them right away, but after a day or so, I don't even see them any more.

If that's not what it is, can you tell if it is monitor or video card related?

I also have an old HP (omnibook 900) laptop with a vertical line down the screen. At first it wasn't noticeable; it seemed to fade in and out. Then as time went by, the line became a little broader and the color seemed to be white with red boundaries. Its fairly broad; about 1/16 of an inch.

I tried seeing if there was a problem with my video connector, but it seemed okay. So maybe its my video card. I tried it was an external monitor, the secondary screen displayed fine. So I concluded that its a problem with the screen - physically damaged. Yup, my lappy has taken quite a beating over the years.

The video card is the hardware interface between the CPU and the monitor. For most practical purposes you might consider it to be a computer itself.

Your problem sounds like one of the monitor row drivers is defective.

Does the line persist if you apply a little stress to the frame of the screen?

Yes as a matter of fact the line completely disappeared simply by applying some pressure as to stretch the screen. However the line came back again about 2 min later. What is the deal?

Eezekiel, it seems like a bad screen. But to be sure, have you tried the other suggestions that I posted or from the link that NoTime posted? According to one of the posters, disassembling the display setup, along with fiddling with the connectors and the inverter board has fixed the problem.
