monitors

Try the monitor on another computer. If it works on another computer, then it is the video card. If it does not work on another computer, then it is the monitor.

Generally, displays coming on with lines either vertical or horizontal are problems with the monitor itself and not the video card... see:

... for further troubleshooting.

I think that's a static line used in Trinitron monitors. As far as I know, you can't get rid of it, you learn to live with it.

Assuming that the monitor itself is bad, you need component level circuit board repair knowledge, and skills for working with high voltage.

The voltage inside the monitor ranges from 5 volts DC to 120 volts AC to 45,000 volts DC. Both the 120 VAC, and the 45K VDC can cause mussle spasms and heart stoppage.

Monitor repair is best left to a trained technician.

Unless the monitor is new, or large (19" or larger) it will be less expensive to buy a new one than to repair the one you have.

Answer two mentioned one point. Trinitron monitors have two horizontal lines seperating the screen into three equal sections. They are most apparent on light backgrounds and are not removable, they are part of the grille. I don't think this is your problem though. The only time I have seen vertical lines they are from the screen being positioned too far to the right or left and actually rolling over on itself or from EM interference, do you have fluorescent lights?
