It will help you just as much as wrapping a rubber band around the
video cable. Sure, the rubber band wont do a damn thing for you, but
it will cost a lot less than $30.00 ;)

You dont need a sync adaptor. Your monitor has 5 BNC connectors, and can
thus accept separate sync. This is a GOOD thing. Especially since your
video card generates separate sync.

Now, you say that some source mentions that the monitor is not VGA
compatible. Most likely, this is because the monitor doesnt support
a 640X480 _at_ 60Hz mode. When IBM compatible computers boot up, they always
use this video mode, and later in the boot sequence they switch to
whatever mode you specify.

SO. IF this monitor is going to work at all, what you need is a video
cable with 5 BNC connectors on one end, and a HD15 connector on the
other. If the monitor doesnt support 640x480, then you would have to use
another monitor to set windows to the correct resolution and refresh
rate, and then switch monitors. Thereafter, when the machine is booted up,
the monitor would not sync up until the boot sequence reached the point where
it changes to the correct resolution and sync rate. Of course, if something
goes wrong, you wont have a clue whats wrong until you switch monitors...

Dont pay more than $15 for the video cable, and make sure it comes with
a toroid of some sort. As long as you're sure your IBM video card can be set
to that maximum resolution and refresh rate that the monitor can handle,
I would say this has an excellent chance of working.
