Help with understanding FOV

Hi, I don't understand why in editor mode the FOV is set to 60 and in the game mode it goes to 111,84, but the visible space it s the same of 60. If i change in editor mode the FOV with a greater value than 60, dont change anything.
The FOV is fixed to 60? Why the htc have a 110 field of view and i see a 60 FOV?

Thanks
