iPadMini2 (retina) full resolution

Hi all,

Deploying project on iPadMini2 leads to poor resolution (1024x768).
Console Output print message

LogPlayLevel:Display: env: LogRenderer:Warning: Reallocating scene render targets to support 1024x768.

How to get the full resolution (2048x1536)?
I’ve already tried to add a DefaultDeviceProfiles.ini file in my [project]/Config folder with lines added

[iPadMini2 DeviceProfile]
+CVars=r.MobileContentScaleFactor=2

taken from here, without sucess.

Playing with the Device Profile Edtior, adding the console variable r.MobileContentScaleFactor set to 2 in the iPadMini2 profile, doesn’t work neither.
Any trues?
Thanks by advance.
