When using the proprietary Nvidia drivers 331.113 or 346.35 the output from one window is often stretched to cover both by Unity. The standard xrandr-based Displays panel in System Settings shows both outputs, but nvidia-settings shows only the external monitor. 304.125 doesn't detect the monitor.
WORKAROUND: Use another window manager.
WORKAROUND: In Unity, manually configure the display output locations and sizes in ccsm.
WORKAROUND: Use nouveau.
