TwinView only works with two monitors and only with a single video card. The
OP is using three monitors and two video cards so TwinView is not an option.
I have a dual monitor single card nvidia setup that I currently use with
xinerama since TwinView does not support per-monitor LUTs (IE. TwinView is not
suitable for color critical work) and I have not noticed any performance
issues with xinerama vs. TwinView. What is missing with xinerama is the
ability to dynamically resize the displays.
