Sorry, perhaps I should have been more clear. I know it's a 15khz CGA monitor. What I meant by "VGA connection" was the type of connection for interfacing with an arcade board or, in my case, a PC for running groovyMame; the type of port it uses to connect. So here, I meant for the colloquial term "VGA connection" to mean a DE-15 connection, or your standard analog computer monitor connection. I have a billabs 24.5 inch tri-sync monitor that can connect to a JAMMA board, or to a PC via a standard DE-15 port, so I guess I was asking if this monitor was similar to that, and could connect directly to a PC.
