I don't know that we are talking about the same thing. Here is a picture of the page in the manual. The only change I made was taking the jumper off J2 on the I/O board. It was installed, therefore on the "Negative Sync" setting.
Wow, thats even more strange that it didnt work. I would expect that monitor to work better via Negative SYNC then Positive SYNC. Odd for sure.
