We have an issue with laptops using external screens as second monitor, this causes a ground loop and interference on the second display.
I have done a fair amount of research and found 2 solutions, the first is to disconnect the ground on the mains lead for the second screen, obviously fine until PAt test comes around. The second is a "VGA Ground Loop Isolator" and I cannot find any re-sellers of these.
Has anybody had the same problem? What solution do you use? Do you have a source for ground loop isolator's or a different solution?
Thanks in advance
