Clone display Geforce FX5200

Hi to all.

I am new at this site. Found it most interesting and I have learned quite a few things from the site.
I need some help. I am trying to clone the display to be able to view on the TV and monitor at the same time. I am using the Geforce FX5200 on Windows XP SP2. I have managed to display on the TV using a single display, ie the computer monitor switches off. I went to control panel, clicked didisplay, settings, advanced, chose the Geforce FX5200 tab and clicked on Nview Display Settings. BUT In Nview Display Mode only the Single Display is available. I downloaded the latest drivers from the Nvidia website but still clone is now available. What am I missing out?

Any Help will be greatly appreciated.
