Configure TwinView option....dual monitors

[hornet77]

I have a Dell PC with a NVIDIA Quadro FX card. I am running RedHat Enterprise 3 as the OS. I can get one monitor to display correctly, but the other monitor displays weird green and blue squares all over the place when X starts. I've configured the /etc/X11/XF86Config file with the following options under the "Device" section:

Option "TwinView"
Option "SecondMonitorHorizSync" "<my-settings>" (same as HorizSync in Monitor section)
Option "SeconMonitorVertRefresh" "<my-settings>" (same as VertRefresh in Monitor section)
Option "MetaModes" "1024x768,1024x768; 800x600,800x600; 640x480,640x480"

I tried this and rebooted, and got the same results. I've also tried adding the options "TwinViewOrientation" and "ConnectedMonitor", but again I got the same results. I've also tried adding a second "Screen" and "Monitor" section in /etc/X11/XF86Config and got the same results.

What am I missing?
