Nevermind, deleted the monitors in the device manager, let them be reinstalled, went to my display properties and the old settings were back. Silly me.
I'm having the same problem with my 8800. I jus tpicked up a 24 inch acer and im trying to use it as my main display and use my old 20" as a web/other program type monitor. The only options im finding are clone and span looks like complete crap.
