I read on my old arcade monitor that it said to make sure to use an isolation transformer. Can someone tell me what this is? Where can I get one? The monitor I can see a power cable sorta like the power cable for an HD but only 2 connectors. Where can I get soemthing that I can plug into that so I can power the monitor with a power strip? Or do I have to use the isolation transformer? Waht is it? Where can I get it? Thanks
