Forums -> Multiple monitors -> Matrox G450 sync pulse polarity

Does anyone know if the Matrox G450 control panel allows you to change the polarity of the sync pulses?

An ATI driver does allow this but I'm troubled by their Win2K idiosyncracies, and looking to Matrox.

----------------

System is 4 monitors (including 2 Sony GDM1950s that are fixed frequency 1280x1024) but two PC's, one 1200 MHz running 98SE (for video capture) with an ATI Radeon VE DH and another with Win2k (for macintosh compatiblility) with two old S3 cards. Because of the scan frequency used during boot, both units boot through a KVM switched mutlisync monitr and then fire up the hi-res monitors.

My real problem is somehow when I ran in the Win2k OS again it dumped a hack to the S3 miniport driver that inverted the sync and also allowed two s3 cards to coexist. Rather than re-invent it I am toying with a more modern video card. If anyone knows how to get a Trio3D and a Trio 32/64 to work again I might be able to resurrect it though?

I have a G200; PowerStrip will change the sync polarity.
