You have to tweak the r.MobileContentScaleFactor parameter in the Device Profile Editor (Window menu, in main editor toolbar). Natively iOS profile it’s configured for non-retina screen.
But… since 4.2 it does not work anymore for me. A walkaround I’ve found is to add a DefaultDeviceProfiles.ini file in YourProjectLocation/Config folder. Paste this (as my iPadMini2 is recognized as generic “iOS” plateform, I changed it for all iOS platforms):

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

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

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