correct resolution for wide aspect monitor


I have Fedora Core 3, and I am trying to use a Sony sdm-p234 monitor with its native resolution which is 1920x1200. Any help is appreciated.
I can't get anything better than 1600x1200 which is the wrong aspect ratio.
I have made multiple changes to my xorg.conf file, the only one that seemed close was adding this change that I found online:

Section "Modes"
Identifier "16:10"
Modeline "1280x800" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync
EndSection

This was still the wrong resolution, but it was the only thing that did give me a wide aspect ratio. I tried changing some of the numbers and any change bring back 1600x1200.
I have also found modline generators online, but I don't know enough about this type of thing and I can't make anything work.

Here is my current xorg.conf file. It displays in 1600x1200, and it is 1920x1200 that I need. I generated the Modline with the help of this site http://xtiming.sourceforge.net/cgi-bin/xtiming.pl.

# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# To customise the XKB settings to suit your keyboard, modify the

# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"

# Option "XkbOptions" "ctrl:nocaps"

I'm not sure how to generate the modeline, but could you post the output of the x-server when you try to start it with 1920x1200? Either do a startx >& x.log or if you use a graphical login manager check in /var/log/ and post that here. That output might include some information on why it is not allowing the 1920x1200.

Have you figured out how to get 1920 x 1200 to work with your Sony SDM-P234 monitor? I just bought that monitor and am also stuck with getting no better than 1600 x 1200 to work. I have Fedora Core 4.
