How to use Media SDK with an additional external graphics card?

Hi,

When I use Intel internal GPU only, I can execute my developed application with Media SDK normally.

(eg. sample_encode.exe)

However, when I plugin an external graphics card, and enable both graphics devices (output to 2 displays for each), the application can not work at all.

The arguments I use is:

sample_encode h264 -i input.yuv -hw -d3d11 -mux -o output.mp4 -f 25

Any idea about this issue?

[updated] then I found that -hw and -d3d11 can not be used together in this scenario. Still wonder why.
