i experimenting desktopduplication api sample code , mentioned here
even full screen directx applications can duplicated.
also here mentioned
the following components of operating system can generate desktop image:
the dwm composing desktop image
a full-screen directx or opengl application
an application switching separate desktop, example, secure desktop used display login screen
however when tested sample code multiple monitors provided here, worked fine other applications running on desktop when started fullscreen directx application, running applications in background pushed onto secondary monitor , secondary monitor captured in duplicated window.
what might reason this? ran exact sample code provided msdn. there more need in order capture directx fullscreen games using desktopduplication api
