Bigger Monitor, same resolution, different display scaling - Aiming feels off

[r3d84]

I went from 23,8 inch (Dell S2417DG) to 27 inch (Dell S2721DGFA), both are 1440p. The 24" was on 125% (recommended) windows display scaling and the 27" now is on 100% (recommended) display scaling. Resolution is the same, physical size shouldn't matter, I think? So I thought it's maybe the difference in dispay scaling...but aiming feels a little bit off in Warzone and CoD Vanguard Beta.

My mouse (Logitech Pro X Superlight) is on native 800 dpi, 1000hz and Warzone ingame sense was 5.0 (relative / 0.00 monitor coefficient), affected 110 fov and 34.63 cm/360.

Is it possible that my sense feels different, or is it just because I'm not used to the bigger screen yet....aiming still feels weird to me.

Thanks a lot

1) PPI
2) size
3) scaling in windows changes the sensitivity, always when you start the game - should be 100%, when not playing - you can return to 125%
4) Mouse testing program. Mouse movement is physical X'Y movement, pointer movement is cursor movement. They should be strictly the same. https://drive.google.com/file/d/1DrAyu3fgnmuHlyAVvIH0lV0yA1Qi6EgB/view?usp=sharing
5) Enhance pointer precision - if enabled, it will also interfere and the program will show it. Also if needed, a file that cuts "enhance pointer precision" from the registry. Some games ignore the disabling (unchecking) and use from the registry. The file will remove the function completely and games can not use it in any way.

Afterwards you have to reboot

1) PPI
2) size

I calculated my new DPI with the following tutorial, which includes PPI and monitor sizes: https://www.igorslab.de/en/from-dpi-and-ppi-to-the-correct-settings-everything-worth-knowing-about-computer-mice-basics/2/

4) Mouse testing program.
5) Enhance pointer precision

I know the Mouse Movement Recorder and used MarkC MouseFix before. Enhance Pointer Precision was always off.

I didn't know that when I used my 24 inch 1440p monitor, so I always had it on 125% scaling. The only thing I did was overriding high dpi behavior by application, in the game .exe properties...but this wasn't given all the time.

Now I'm on 27 inch 1440p and 100% scaling. I am wondering, people say 200% scaling gives 2x mouse speed...so 400dpi on 200% is like 800dpi on 100%. If that's the case, even in games, then my dpi and/or ingame sense felt like 25% faster all the time?

So if that is the case and I'm on 100% now...with a ingame sense of 5.00 - I actually have to add 25% to my ingame sense, to match the 125% scaling before? Like ingame sens of 5.00 with 125% scaling is like ingame sens of 6.25 with 100% scaling?

Thanks

I don't know how windows scaling works for games, but the principle as you described, if we take 1920x1080 and we have 400dpi, if we put 720 and stretch it, 400dpi x2 get 800. If we don't stretch 720 in the game and play in the black bars, the 400 dpi will stay the same on the monitor, that is, there will be no increase.

As for the multiplier in the game and dpi, the shooting is on a 2D monitor and the movement is on a sphere. There is a fixed distance of 360 and people write about it as "sens" in the game.
Let's say we have 20 cm, and these 20 we will feel on a 2D monitor at different FoV 120 and 60 in WZ, at 60 sharp and at 120 inert.

You can also measure the path in monitors and pixels:
360\120=3*1920=5760 total path in pixels
360\60=6*1920=11520 total path in pixels

S=c(monitors); t=l;

When the angle of view changes, the speed of the pointer changes, the path does not change, the path is a circle 360=20cm. When the viewing angle is 60, to cover the distance, you need to spend from edge to edge 6 monitors, but you need to match the path of 20cm on the mouse pad. At 120 it is already 3 monitors, and since the monitors are physically the same - one characteristic in length, in order to traverse a circle of 360 degrees around its axis, the cursor must move slower. Therefore, when setting FoV 120, there is a fisheye effect and the cursor becomes inert. If you set it to 60, the cursor will be very sharp, despite the fact that the character will move as if slowly, it will be difficult to aim. 120 the character will be fast, but the cursor will be inert (slow). This is all related to the multiplier "a", it starts to appear and affects the fact that the equality is fulfilled. Multiplier "a" depends on viewing angle, speed (speed depends on viewing angle, but in general they are complex)

c,l are length units (cm, m, inches, pixels, etc.)
C(the length of the circle in the game)=a(the product of some multiplier)*l(the length traveled by the mouse on the mouse pad). The a1 multiplier depends on the viewing angle(60), on the pointer movement speed, on the sensitivity in the game, not on dpi, sens. - is the speed of the pointer movement.
The "c, l" of the path depends on dpi. The speed of movement depends on "sens. 

let's hypothetically imagine that the path of the mouse from edge to edge on the mouse pad equals one monitor. For the equality 6=a60*1(figuratively, these numbers(6;1;) are not values, they include a complex of numbers) and 3=a120*1 for this equality to hold, a60≠a120. That is, the multipliers "a" are not equal, that with different viewing angle, different dependence of "v" speed, different dependence of "sens." sensitivity, we can call them synonymous v=sensitivity, sensitivity=v.

Thanks for the detailed post!

For 2D sensitivity, your cursor moves slower on the 27", at 0.8x the speed.

For 3D sensitivity, your sensitivity will feel faster on the 27", 1.125x the speed.

This is because you have the same field of view on the new screen, even though it is a larger size.  You need to have a higher fov on the larger screen, maintaining the original 110 fov within the 24" portion of your new 27" screen.  Using 110 on the new 27" is the same as using ~103.5 on the old 24".  If you want to have identical sensitivity, you need to increase the field of view on the 27" to ~116.2. If you don't adjust the fov, you would have to reduce your sensitivity by 0.888x instead (cm/360 will increase by 1.125x), which will be identical to converting from 110 fov to 103.5 fov using monitor distance 0%.

 

tldr: You need to use 110 fov on the 24" and 116.2 fov on the 27".

Thank you so much! There is so much input and I did so many maths......could you maybe tell me short...what exactly I have to use, to transfer my old 1:1 to my new monitor?

Old: 24" monitor / 1440p / 123 ppi / 125% windows display scale / 800 dpi / 110 fov / 5.00 ingame sens

New: 27" monitor, 1440p / 109 ppi / 100% windows display scale / 800 dpi / 116 fov (your advice) / ??? ingame sens

So adjusting my fov from 110 to 116 is one thing, did that now. Are the different ppi and display scaling still affecting my sensivity on top of this fov factor...or does the new fov already consider and include these factors? So fov 116 with 5.00 ingame sens on my new 27" monitor will be 1:1 the same as 110 with 5.00 on my old 24" monitor?

Once I have the settings right, I can save and convert them to other games...just this new size, ppi and scaling confuses me like hell. Looking forward to your answer, dude. Thanks so much.

You only need to change to 116 fov, everything else can be the same. It will be the same as using your 24", except the extra 3" is providing extra fov.
