Use the nVidia X Server application to set it up, and write out the
new /etc/X11/xorg.conf file. <----don't forget to do that, which should
resolve the resolutions bit as well!!

Then use your system preferences bit to complete the desktop settings.
You should be good to go, that is how I set up mine. I set up my display
to be one display 2X wide across both monitors. Works perfectly for me.
