Googling with 'Xorg nvidia dual monitor' will result in a heaps or
wikis. Even a 2013 post will be relevant given your antique GPU and driver!
First check this locations for conflicting device, screen and/or server
layout settings:
/usr/share/X11/xorg.conf.d/
/etc/X11/xorg.conf.d/
nvidia-settings and its GUI can't adjust all X.Org parameters, since
'root' is needed to save those functions and X does not read $HOME.
You'll still need a proper xorg.conf file to tell X.org what to do. The
APPLY button is for Monitor and GPU parameters that do not require the X
server to restart or reset.
The Nvidia has has an extensive README.txt that gives lots and lots of
information on setting up the driver. I assume you want your one GPU to
drive 2 monitors of different resolutions as separate independent X
screens s. You can also set up a single X screens spanning both monitors.
http://us.download.nvidia.com/XFree86/Linux-x86/304.135/README/
Here are 2 methods (There is a third involving the xrandr utility, but I
will leave that as a exercise for the reader).
1. Run nvidia-settings GUI as root or (ugh) sudo, click "Advanced..."
button, and configure the settings the way you want. Then, instead of
"apply" click on "Save to X Configuration File" and save to
/etc/X11/xorg.conf.d/xorg.conf
Name can be anything ending in .conf
Restart X.org server.
2. With older nvidia drivers, monitor (DPI, and a few other
autodetection issues can occur. Edit the above xorg.conf to fine tune,
for example (I've left off the non-GPU settings for clarity, and the
values are for my particular hardware - adjust as needed). Once you get
something that is close, you can then use nvidia-settings GUI to fine
tune and save to xorg.conf.

Hints:
you can use 'xrandr --screen [0 | 1]' or 'nvidia-settings -q dpys' to
determine which GPU port (VGA,
