someone could do a recap for those respective kinds of monitors every once in a while, but you'd have to get one of the spearheaders to do it since most of us are like you and just following one kind, or someone who understands all this could do it...
as for the arcadevga tryout (vibez), just hack the appropriate cable to plug into the second arcadevga output, and then go to preferences (from the desktop) and output to a second monitor. since i can't try it out, i can't tell you exactly what to do. you might not be able to do it at all since windows might not see another monitor hooked up, or like alan said, it might not work due to a different signal or poorer quality. it's not too big of a deal to try out, since we should be able to do it our original way by splicing in our gun between the monitor and the card. good luck if you do try it.
