The resolution in the ini sounds perfectly fine, the launcher doesn’t show it correctly. Your issue is almost certainly is not related to the resolution.
First and foremost make sure to reset the game’s profile to its default values before you continue. You can do that on the trouble shooting page of the vorpX config app.
If you want to try without the resolution auto setting and set a resolution manually instead, you can disable it for troubleshooting purposes in the config app (“Never change any game settings”).
