Is FH4 FOV a horizontal or vertical FOV?

Coming from a sim racing background, it’s not clear… and also why are the FOV settings so badly capped? I’m using super ultrawide monitor 5120X1440 at 22" inch away… I need 93 FOV horizontal!!

It’s a horizontal stretch I believe, ultrawide monitors are supported but they distort to the right or left of the screen depending on the car being left or right-hand drive…and the sliders are all they give you to work with. Why? Don’t know.
