There's a paragraph in the FOV section which begins with "If the game launches "zoomed in" on high resolutions and only part of the screen can be seen"...
A) This has nothing to do with in-game FOV and is a result of the game not detecting Windows DPI scaling properly.
B) The proposed solution doesn't work for me in Windows 11 22H2. The only working option is to disable DPI scaling - i.e. set it to 100%.
I'm not changing the page because I'm not sure if the solution works in some other Windows version like Win10 or something.
