NO CLONE, help here pls..

Hi to everyone, hope you can help me on my problem.

The problem is that i cannot clone my geforce 7200 GS.
It only appears "single view", so I just can see on my monitor, or on my TV, but cannot see on both.

I put you here 2 images:

The first one: You can see that the ONLY option that it appers is "single display"


Here the second one: You can see that TV it´s "detected", but i wanna clone and I can´t do it
!!

I put here my PC description:

Pentium[R] 4 CPU 3.00GHz
512 MB of RAM
Graphic Card: Geforce 7200 GS


Things I did without solutions:

Try with another Monitor
Try with another driver
Try changing resolution and Hz settings
Try Force TV detection
Try TVtool application


If you have any idea, please help me

Thanks for your attention
