27 inch Monitor vs 24 inch

[jared0215]

Sorry if this has been asked already but im struggling to find an answer. I play counter strike heavily and a few months ago I switched from a 27inch 60hz monitor to a 24.5 inch 240hz Monitor. I have always played in the same Sensitivity and Resolution ( 1600 Dpi .6 Sens)(1280x960 Black Bars)  My question is does the size of your monitor affect your sensitivity? My sensitivity seems off all the time and ive been trying to switch from .525, to .7, and .55. Nothing feels comfortable anymore. At first I thought it was just me getting used to the smoothness of the 240hz but its a been a few months now and ive seen little to no improvement.

Technically no, but it can be perceived differently as you are experiencing. I would think several months should be enough to settle in though.

Try 0.661224 sensitivity. That will scale the sensitivity to the new monitor size, but your cm/360 will obviously be different because it isn't 0.6 sensitivity. You probably won't even prefer it though since you have become accustomed to different settings for a few months.

How did you get this number if you dont mind me asking

Sure.

What you want is to keep the same ratio between your rotation circumference (cm/360°) and the projection circumference (calculated with fov, and monitor size).

If you adjusted the Mouse CPI so that the physical cursor speed is identical between the two monitors (you preserve the same ratio between the cursor and mouse for physical distance traveled), you would have increased it from 1600 to 1763.265 (1600 * 27/24.5). That alone would have preserved your cursor speed and camera speed at 0.6 sensitivity.

Since your Mouse CPI is still 1600, the game sensitivity has to change instead. Luckily CS:GO has a simple sensitivity system. You can do: 0.6 * 27/24.5 = 0.661224.

This works because the rendered image of 90° (horizontal 4:3) on a 24.5" monitor, is equivalent to ~95.56° (horizontal 4:3) fov on a 27" monitor, which is a magnification change of 27/24.5, the same change as the change in cursor speed.

(360 arctan(27/24.5 * tan((90 * pi/180)/2)))/pi = ~95.56°

If you go from 90 fov to ~95.56 fov, and scale the sensitivity by the change in magnification (monitor distance 0%), you would go from 0.6 to 0.661224.

 

If you want to have the 24.5" monitor exactly equivalent to the 27" monitor in camera speed AND rotation distance, you would have to decrease the 24.5" fov, which isn't possible in CS:GO. You would have to drop the FOV to ~ 84.44°.

This is really interesting. I was thinking that since the screen was smaller I would have to go to a lower sensitivity. (I know nothing about this stuff )

I edited to add a bit more information.

Interesting, but what if he had also and aspect ratio change?

Yea if you go to a smaller Monitor lower sens as he showed in the calculator if you go to bigger monitor you have to increase your sensitivity
