Monitor refresh/sync rates

I am looking for the verticle refresh and horizontal sync rates for a monitor. I checked the mfg’s web support site – no relevant info. I checked several other web sites, searched google, no good. I called the mfg and they don’t even have the info in their internal database. Does anyone here have a really good source for this type of info on older monitors? The monitor in question is a Micron 15FGx (MMN001004). It still works fine, and I am planning on using it on a FreeBSD machine, thus XFree86 needs to know this info.
