Ati/AMD Hydravision

On my old computer I had an ATI Graphics card and I used a program called Hydravision which is a multi-monitor support program.

My new computer has a NVIDIA GeForce GTX660 GDDR5 graphics card.

NVDIA has a program called NVIEW but it does not support my new graphics card.

Is there anything out there that will work like the ATI Hydravision program with my new card?

Thank you,
