When loading the game for the first time, the game did not default to the resolution of my monitor (3440x1440). I can't remember the resolution but it was sub 1440p.

Going in to the Display Options to set it to the correct resolution, the resolution dropdown only presents as many resolutions as will vertically fit on the screen. It doesn't give the ability to scroll through the list and hence select the correct resolution.

I assume an alternative is to edit the 'resolution' property in the JSON in the Options file?
