Perhaps the problem is with the mouse, then, not the screens.
I've had best results with two 22-inch monitors, everything either maximized or divided vertically (two tall windows). Tiling window managers work very well for this, as does Emacs. Switching between the monitors and different workspaces via the keyboard helps tremendously.
