[RESOLVED] NCD monitor

I (mistakenly) bought a NCD model NC2185AA 21" monitor, then realized it has a 5BNC connection. I'm confused as to whether it will operate successfully on Windows 98 with a REAL 3D Starfighter i740 AGP (8Mb) video card. Some say it's a fixed-frequency monitor (56-85Hz hor. scan & 60-120Hz vert. scan) and won't work on this card. Others say that by virtue of it being a 5BNC connectiod, it will likely connect to my VGA port and work w/out a problem. I'd like to be sure. Which would fail first if I connected it, my video card or my monitor?
