SetDisplayConfig fails from metro app on windows 8

Question

SetDisplayConfig fails with ACCESS DENIED error on windows 8. what is the alternate api to configure displays from a metro app?

Answer 1

SetDisplayConfig is available only to Desktop apps.  There is no analog for Metro style apps.

If you look at its definition in winuser.h you will see that it is defined only for WINAPI_PARTITION_DESKTOP .  See http://msdn.microsoft.com/en-us/library/windows/apps/br205757(v=VS.85).aspx for information on Win32 API available to Metro style apps.

Answer 2

WinP works from Metro,  Is there any API to use WinP capabilities in metro app? Whats the reason for blocking display config api's in metro apps?

 

Answer 3

Win-P is a user setting and users can use it.  System configuration itself is limited in Metro style apps?

What is the scenario you have that requires the application set this rather than the user?  If this is going to severely impact your application then please provide feedback via the Feedback tool or connect.

Hi Rob,

I faced a similar problem where we are trying to include the display capabilities for one of the devices into metro styled- device application as demoed in Build. How come basic API like mode change has not been given in metro?
