question about nView display mode

[yy3d]

I have xp pro and a GeForce 2 pro with the latest drivers. I'm trying to enable a clone view in the nView display mode but the only option I have is "Single display" in nView modes. I can switch between the monitor and the television in Current display box but what I want to do is view on both the monitor and the television the same thing because if I move the display to the t.v. it's difficult to to see and control what is going on via the tv. Can somebody please tell me why I don't get a clone option with the gf2 card? Thanks
