I am practically GIVING you the answer at this point.

To allow you to use this formula, here is the general layout of my monitor/viewing distance. Note that this probably won't equal 23.5 degrees exactly, because I calculated in a much quicker and rougher way. But it'll demonstrate the point.

My monitor is approximately 100 cm away from my face. It's viewable area is 40 cm wide. This gives you all you need to solve that formula;

viewer distance = (screenwidth)/(2*tan(FOV/2))

100 cm = (40 cm) / (2*tan(FOV/2))

Solving algebraically comes up with, finally;

FOV = 22.61986494!

As you can see, according to Valve's 'optically correct perspective' formula, I would need to set my FOV to 22.6.

So what does that tell you about my problem?

That you're flying in tunnel vision... pure and simple
