Monitor Out of Range Error with xf86

[Patrick Carlson <firefly2442@gmail.com>]

Hello.  I brought my AMD64 system home over spring break and I'm
trying to configure it for another monitor.  Whenever I try to
configure with xf86config, and startx, it the monitor goes gray with
wavey lines and says "out of range".  I looked up the properties on my
gateway EV900 monitor and everything seems correct.  I can't seem to
figure out what the problem is.  Everything works great with my other
monitor.  If anyone has any suggestions I would greatly appreciate it.
 Thank you!
