I am trying to add a third monitor to my system but when I change the setting to use all three it will only use mirror mode.
It does show all the same thing on all 3 screens, so they all work (I think).
If I change it to just 2, it works fine and the desktop extends.
This is a laptop if that matters.
One screen is laptop screen, other 2 are optiquest (which are detected as viewsonics).
I am pretty new at this stuff, so please go easy on me.

Thanks for any help,
