Hi,

I'm trying to drive an Hitachi 4619 (the c model) using a matrox millenium
and XFree86's 3.2a server which supports sync-on-green by now. I'm lucky to
own a fixed frequency card based on some Trident chipset, but unfortunately
this cards is dying on me. Thus, my first idea was to copy my old modeline
and simply try it with the matrox card.

Now, when I plug in my new card, it seems like the monitor manages to sync
vertically, since the picture is not scrolling. However, it looks like
it's not recognizing the horizontal signal as I can see my screen three
times. It looks a bit like every third line is horizontally shifted by the
same amount. (I really hope you guys understand me here...). I played a bit
with this modeline, but my problem won't vanish (which is no suprise - I had
no clue what I was doing). Do you have an idea what I could try?

Here's the line:

ModeLine "1024x768" 65 1024 1024 1267 1351 768 768 796 809 -hsync -vsync

The cable I'm using came with my old card and has 4 BNC connectors. The
Hitachi monitor supports external composite sync as well as sync on green.
I figured I can reuse this cable by not connecting the composite sync line,
since the matrox will supply this signal on the green line. Is this true?

Any help is greatly appreciated

Ciao
Thilo
