While my main monitor was out, I figured I would try and re-route the connection to my top monitor - however, I get no signal. This has happened before, and I fixed it by re-connecting the main monitor to the same power supply (isolation transformer) as the top monitor - is the top monitor not displaying video, because its being given overvoltage? (The power wires for the two are shared, so is it possible that by being un-connected the top monitor is getting too much?) Second question, if I disconnect the top monitor too would anything happen to the isolation transformer? Seeing as how the voltage is being put in, but not going anywhere else.. I'd like to test some of my games, but not too happy with leaving a malfunctioning monitor online. Thanks
