You can use CheckInterfaceSupport only to check whether a Direct3D 10.x interface is supported, and only on Windows Vista SP1 and later versions of the operating system. If you try to use CheckInterfaceSupport to check whether a Direct3D 11.x and later version interface is supported, CheckInterfaceSupport returns DXGI_ERROR_UNSUPPORTED. Therefore, do not use CheckInterfaceSupport.

for (int i = 0; dxgiAdapter->EnumOutputs(i,&pOutput)!=DXGI_ERROR_NOT_FOUND; i++)
