So, about that little red light...

Another quick look at your post, and I saw this

I agree with this, but this is irrelevant to assess which FOV correspond to your normal real FOV to the monitor.
This is another example of (and perfectly illustrate) the fact that a standard monitor can't give you a peripheral vision AND respecting at the same time the object size according to the FOV.
Either you have correct object size accoring you narrow field of view allowed by the narrow window of the monitor OR you have peripheral vision and reduced size of objects.
You can't have both at the same time EXCEPT if you're using a semi-hemispheric screen (what you have in real prophetional simulators).

As we say here, you can' own at the same time the butter, the money of the butter, the milk, the cow and the cowgirl...
