Has anyone successfully used an ArcadeVGA with a Hantarex MTC900E?  I can't seem to get it to work.  I know the monitor is good because it works w/ a trident card.  But, I would like to run Windows.  I have tried it with and without the Ultimarc amp but no success.  I have tried adjusting horizontal and vertical pots, but I can't get the picture to be correct.  At it's best I can make out the Windows logo's, but it's like there are 2 of them.
I have tried composite sync, separate horitzontal and veritical sync going to both positive and negative sync on the monitor.  Do I need to do anything special with the ground?  I basically just have ground from the video amp going to the ground input on the monitor.
Anybody have any ideas??
Thanks
