How to set resolution of packaged game

[dev100000]

Another way is to create a file called DefaultGameUserSettings.ini in your <ProjectName>\Config folder with the following contents:

[/Script/Engine.GameUserSettings]
bUseVSync=False
ResolutionSizeX=1920
ResolutionSizeY=1080
LastUserConfirmedResolutionSizeX=1920
LastUserConfirmedResolutionSizeY=1080
WindowPosX=-1
WindowPosY=-1
bUseDesktopResolutionForFullscreen=False
FullscreenMode=2
LastConfirmedFullscreenMode=2
Version=5

Yes, but I need to as an option in the game, so that players can change resolution.
The node above does not work! Am I missing something for this node to work with a shipping built?
