All of a sudden a thin vertical line of bright, primary green has appeared on my monitor. I am pretty much convinced that it's a hardware problem, which is something I can live with, as this baby has served me very well for many a year and I guess it was only a matter of time before something like this happened. But I was wondering if a single line of pixels on the monitor developing a fault is something I should take as a sign of more monitor problems soon, or not.
