Question NVidia 6800 TwinView - TV treated as main monitor


I'm trying to set up TwinView on my Nvidia 6800 graphics card to use my LCD monitor and TV.

Everything is working, the only problem is, the TV is treated as the "default" or "main" monitor, and the LCD as the secondary I.e. the GDM login screen, GNOME desktop, etc. appears on the TV, not the LCD monitor. How do I specify which monitor should be the main and which should be the secondary?
