Is it possible to use multiple monitor output with one GPU-card?

Hello all,
I have developed some color processing software on CUDA.

However, I’m struggling to output 4k2k display directly from GeForce GTX285 card.

The card has two output monitor so I want to relate one GPU to multiple Direct3DDevice or OpenGl devices. But second cudaD3D9SetDirect3DDevice() on same GPU failes with cudaErrorSetOnActiveProcess ( as described in manual ).

Is there any way to relate multiple monitor on same GPU so that transfer video buffer to both monitor faster? Any hint is welcome.



Any one can help me?
