Win 8 Smooth Screen Rotation in Win 32 Application

Hello,
 

Good day!
 
Currently, I am trying to rotate the screen manually using the ChangeDisplaySettingsEx API
in Win 8 and it seems that the rotation is not smooth as with if we tilt the system. Can you help
me identify which API that can rotate the screen smoothly?
 
I have tried this Windows::Graphics::Display::DisplayProperties::AutoRotationPreferences
but it seems that it only works when the application is active. By the way, I am developing a
Win 32 program.
