I have a question regards to SwapChain usage. If my video card (represented as IDXGIDevice) that is connected to two monitor (represented as IDXGIOutput), what is the best way to present what is on the SwapChain buffers to different monitors under my control? IDXGIOutput::SetDisplaySurface seems has this capacity but document says should not be called directly by application. So how I can control and access multiple monitors in an application? Thanks a lot!

This seems promising, though maybe not exactly what you are looking for.
