What it says in the car is what it is. They can't combine or anything - you only have a single fov at any time. Your setting sounds broken in the menu, though I haven't tried in recent builds as triple screens don't use that setting. You should have steps 10 to 100 stepping 1 at a time.
Default FOV for RF2 is 50 not 60. ( Was at ISI times ) But depends on content. Default for the new 397 Content is 49. Have to use near default because of my tiny 27 inch single setup. Ordered a VR set...
I have a 27in and it's the largest I have ever used. So it doesn't feel tiny to me. I was at default for the longest time, but used the tools to greatly reduce the FOV number and am getting quite used to it. I can just see the bottom of the Cosworth LCD on the S397 GT3 cars. Strangely, due to the distance of the monitor from my eyes, again about 27inche, I was given a FOV of 27. Go Figure.
Single 27in monitor is fine but I was very close ...22in away so my FOV calculated out to about 33 Vertical FOV. Using triples now but still same FOV of around 33-35. You can still adjust it in triples by using the CTRL + = and just manually adjust your distance from eyes which adjusts FOV like you could with single screen!
