Hey guys I recently discover this website and I have been learning a lot with all the info here. I mainly play COD and I was wondering how can I get the best of my aim when it comes to the monitor distance coefficient setting and I have doubts on what is the correct way to set it to. I play 35cm/360 on a 1440p monitor. Thank you in advance.

If there was an objectively correct way to set it up, it wouldn't be an option in the menu. The developer would just set it internally to what is "correct".

It's entirely user preference and just functions as a fine-tune aiming sensitivity slider, where the values represent a percentage of screen space instead of a coarse linear percentage of degrees / count. The same values / methods exist on this website so you can have the same feel and conversion approach from one game to another.

You don't need to stick to any specific numbers, you may find 131.05% is perfect for you and not 133% for a given scope. It's all completely arbitrary.

Ok thank you for the explanation.

You can choose a monitor distance that can be achieved with the same mouse movement at any zoom level using the other option available here, called Monitor Distance Coefficient.

YOu can  change the zoom intensity with your mouse.
