hmm strange i couldn't get it configgured in xp, i use my 22" as main and have my 17" on the left side of it, so if i wanted to go from my 22 to my 17 then i had to go to the right side of my 22 because it sees the 17" as an axtension of 22" so i used a program of nvidia (don't remmember what its called) where i could set it all up
