On my monitor, near the top of the screen I have a few horizontal lines that are pinkish in hue.  At first I thought these lines were caused by the ps2 av adapter I got from ultimarc.  Now I think they are being generated by the monitor itself.  When I tweak vertical hight I can shrink them down a bit, but then I lose the ability to cover the entire monitor with a picture.  If anyone could tell me what I need to do to hopefully fix this I'd appreciate it.  I've attached a picture showing off the problem.  It's a little hard to see (it's not a HUGE problem, but it's annoying). 
Thanks
