Where does the display resolution dialogue box save it's settings?

After building my game and running the EXE I get a dialogue box showing the different resolution options. These values are saved somewhere - I’m want to know where they are saved.

For windows, in the Registry.

Be very careful when viewing the registry, don’t modify anything unless you know what you’re doing

run regedit, then browse to :

HKEY_CURRENT_USER > Software > [Publisher Name] > [App Name] >

you’ll see Screenmanager and UnityGraphicsQuality entries, as well as any playerprefs keys you have created.

Edit: not sure these settings are in the same location as playerprefs on other platforms, but here’s the info on where PlayerPrefs are stored on different platforms : Unity - Scripting API: PlayerPrefs
