I have a Gateway 1440x900 LCD flatscreen, and recently a black line just popped out from no where. I've tried reconnecting plugs, switches, and other things yet the black line is still there. Can anyone help me?

Re: Black Line Across Screen
It's almost certainly a bad connection inside where the mylar strips attach to the LCD.
If this is under warranty, you should contact Gateway.
If it's out of warranty, it's not economical to repair this problem.
It would require a whole new LCD panel, and - believe it or not - that part's cost usually exceeds the price of the monitor!

Sounds like you pulled the TV apart, good luck. Hope you earthed yourself. You could try a replacement t-con board. if that was the problem. http://electronicshelponline.blogspot.com.au/2012/06/how-to-replace-faulty-tcon-board.html
You need to make sure your computer's display resolution is set to 1440x900, which is the monitor's native resolution. Other resolutions will result in fuzzy displays or, as you're seeing, distorted images.
Right-click on an open area of the Windows desktop (that is, not over any icons), then select "Properties" from the pop-up menu. Click the "Settings" tab and you'll find a slider adjustment to set the resolution. If 1440x900 is not offered as a resolution, you'll need to upgrade your video card (or add a video card if you have a motherboard with integrated video). Most newer computers support that resolution, but some older systems may only go to 1024x768.
checkl in your menu or settings if you have inout it to VGA signal...have you tried other mintor in your current CPU if it works? you can scan the input of the signal from your menu and it should be VGA input.
Although I don't have much hope for this, it is what I would try first:
Plug the monitor into a different system to make sure the problem is not from your video card or circuit.
This will probably show the same black line since the signal received by the monitor can't really cause this kind of problem.
I'm afraid that either the LCD panel itself has a failed driver (hardware, not software) or processing prior to this is faulty.
That line is being caused by all pixels being turned on hard, producing the maximum possible black.
Most all of the components inside are placed and soldered by robots and boards are often not economically repairable.
This kind of problem is becoming more common as China takes the plowshares away from farmers and makes assembly technicians of them.
A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.
I too had a black line horizontally across the screen (on a 52" d62). It was brand new and was as if the screen had been "pinched" at the end of the line and it radiated outward (in my case, the "pinch" was at the extreme left and line went out to the right, like a crack).
Mine was a factory defect (right out of the box) and was replaced (2 yr now and no issues). This line of yours may have been there from the start and maybe you just didn't notice it?? Not a slam, just an observation.
The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at.
This set is worked on in the home and does not need to be taken to a shop, so, you can still use it.
