Very Computer

I am running XFree 4.0.2, I have a XF86Config in /etc/X11/XF86Config
with, as far
as I can tell, the proper monitor settings and the nearest adapter
settings.  When I
attempt to get the "1600x1200" resolution with depth 24, I get a very
distorted (illegible
screen) with large horizontal waviness.  This prevents me from tweaking
using xvidtune
unfortunately.

I am using a Voodoo 4500 AGP card (32 MB RAM) by 3DFX (too bad it went
bankrupt.)
I have a 21" Viewsonic P810.  I used the manufactures values for the
scan rates.

If anyone has this resolution/depth with the same videocard (Voodoo 4)
can you please
pass along the Modeline used.  Or if anyone sees a obvious flaw in my
configuration,
I would appreciate knowing it.  Then again, any piece of advice is
helpful.

Thanks for reading this far,

George Houpis
