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.
the controls for focus adjustment are on the flyback transformer, (that big black thing on the left hand side (usually) of the monitor with the thick red wire that goes to the CRT.) the flyback may have 1,2,3 or even 4 knobs on it. 3 of these would be labled SCREEN (bottom knob of flyback. handles brightness)
FOCUS 1 + FOCUS 2 (focus adjustments. these are what you need to play with) and the 4th knob (some old mitsubishi workstation monitors had these) i do not know, it wasnt labled and HV adjustment was on the deflection board
Which type of video connector are you using? VGA or DVI?
If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.
Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.
