Just depends on how close to the screen the eye is. The original post was asking about a big TV, and when moving real close to that one a high fov makes sense. Not when viewing it from a typical TV watching distance of course. But when putting it on a desk like a computer scteen...
Umm... Alright, that makes sense. In an ancient post HiTech said that the correct FOV is like looking out through a window and obviously the view shouldn't bend at the frames. Step closer, see wider. He also presented a formula for calculating the ideal FOV, it all is somewhere in the forums. Anyhow, I suppose we both agree that the right FOV is what looks natural from the point where the eyes of the player are.
With all that said my previous comment about the FOV being more a question of resolution seems misleading. However, since the Video Settings don't ask about the size of the screen I suppose resolution is being used for calculating the default FOV with the assumption that the size of a single pixel is roughly the same independently of the screen diagonal. That works to some extent with desktop monitors designed to be viewed from the arm's length (70 cm/2ft 4"). High resolution laptops and standard resolution TV's don't fit that formula so some adjustment has to be made.
