Not sure about how well it will work automatically, but try running

xrandr

and reading the output. It should tell you what monitors you have
hooked up and what resolutions and scan frequencies they support. I
did this and then put the ones I wanted into my xorg.conf file and was
good to go.

Hope this helps,
