16:9 to 21:9 conversion

[PyroX]

So i'm relatively new to this topic, but i planned to get a 21:9 monitor and i tried to use the calculater, to get the new hipfire sens and probably a new USA (i'm talking about Battlefield 1 btw).

So my USA coefficient for 16:9 ingame is 133% / 1.333333 in the config file which means i have to use a 75% monitor distance right?

But on a 21:9 screen 75% monitor distance is not the same as on a 16:9 screen, because the 21:9 one is phisically wider and therefore 75% monitor distance wouldn't match at the same point in reality.

Also i have taken some screenshots from the calculator, but i don't know if i have done it right, becuase the monitor distance thing confuses me. But if it's right what i was doing, could i just ignore the sensitivities for each individual scope and just use the calculated coefficient, atleast that's what i read on another post, about ignoring the individual scope sensitivities.

For 16:9 it is 75% yes, but the basis for the sensitivity is 133% of the vertical field of view. On a 21:9 you still have the same 133% of the vertical FOV, but your horizontal FOV is now wider. This width is just added on with this conversion, keeping the 16:9 portion of your monitor exactly the same as before.

means i just leave the coefficient on 133%, but increase the dpi because of the higher resolution like that:

(1440 / 1080) * 800 dpi = 1066.66 dpi

 

Also isn't it mathematically correct to calculate the new monitor distance, to match to the old 75% like that:

(16/9)*0.75 = 1.33

21/9 = 2.33

(1,33/2,33)*100% = 57.08%

which concludes into 1.33 again:

2.33 * 0,5708 = 1.33

 

But is the coeffiecient directly related to the monitor distance match like this?

If this is right and i want to convert my hipfire sens to the new aspect ratio, do i use 75% monitor match or my calculated 57.08%, becuase mathematically and logically this seems right to me.
