Where dose the game store the Resolution data?

[Fappy-さま]

If i launch the settings.exe the resolution field is empty.
If i would press ok the game would crash.
Since i could play on the steam deck the resolution on my main rig is the same as on the Deck (1280x800), but on the main rig i want to play in 3440x1440 or at least 2560x1440.
