Screen capture, select the right screen.

Hi all,
I'm using this command to screen capture

./gst-launch-1.0 d3d11desktopdupsrc monitor-index=1 ! d3d11convert ! 
d3d11download ! autovideosink

I have noticed that the "monitor-index" does not represent the real 
display number on Windows.

If I rearrange the monitor order in Windows, monitor index on gstreamer 
does not change.

How can I know how to record the left and right screen if that number 
does not represent the "numbers I see in Windows"?

Thank you
