[plug] dual head 'rolling'

[Simon Scott]

Hi all

Ever since Ive been running dual head one thing has annoyed me - on one 
monitor, I get one dark, thickish line rolling up through the screen and the 
other has one rolling down.

Obviously since the monitors are right next to each other they are interfering 
with each other slightly. Has anyone found a way to reduce/eliminate this 
effect beyond moving the monitors further apart?

I just replaced my aging 15's with a couple of newish 17's... slowly Im 
accumulating more screen real estate :)

Thanks
