DVI Y Cable

The Robot is a large computer that I use for distance trail mapping.  As it is a piece of equipment that I use in volunteerism, it's a part of this log.

I have three monitor computer system.  I have a VGA one as a document monitor, the other two are on a DVI "Y" cable.  If I plug in one of the monitors with the other one on, I'll get lines in the one that's already powered on.  To get rid of them, I just have to power the second DVI monitor on, and then maybe off for the lines to go away.
