You can buy adaptors that do this or make your own (the logic is very simple. see http://cvs.anu.edu.au/monitorconversion/sun.html). Sync on green monitors, however, are not so simple because the logic modifies the green analog signal which makes this a high frequency circuit. I made a circuit to do that once and had it on my old web page back in college - long gone. > > Anyway. If the nvidia doesn't work, Maybe a radeon card would?

The cable adaptor is only a wiring adaptor - it's still ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ I don't know if the 13W3 adaptors have a power line in them. In order for the *cable* to do the sync combining I think it would need active electronics in it, which means it needs power of some sort. So I'm suspicious about the ability of a dumb cable alone to handle the sync combining.
