Will Changing Your Resolution Change Your Mouse Sensitivity?

[jamesconroy]

DPI is the number of a pixels your cursor moves for every inch you move your mouse. My question is, if you change the resolution Windows is running at, say from 1080p to 1440p, will your mouse sensitivity actually feel slower or does the mouse program adjust for that? Also, if you have Windows running at 1440p, but you have your game set to Fullscreen 1080p, will it use the the resolution of Windows or of the game?

I think it does. At least that's how I experience it. I play CS:GO on a 21:9 monitor but I have it set at 16:9 stretched full screen. When I revert back to the 21:9 format it feels like I need more mousepad all the time for the flicks, namsayin

You have to change your mouse resolution to suit 

 

If your gaming at 1080p on a 1440p screen, then your mouse will think the game is 1080p

 

 

I dont recommend 1080p on  a 1440p screen though you will lose quality

1) Yes, that is why a lot of (gaming) mouses have a DPI switch to put it higher / lower

2) The game will be 1080, so the graphics will be 1080p even if the monitor is 1440p

Your mouse sensitivity per se will not change, but your perception of it will. If you're crossing more pixels per inch, you will need to bump your sensitivity up in order for the mouse to feel as fast as it did at lower DPI.

This is a very accurate description. Confusing if nontechy but ACCURATE!

The easiest way is to simply calculate the difference in horizontal or vertical pixel distance from the two resolutions, then increase mouse sensitivity by that same percentage.

Increase = New Number - Original Number

% increase = Increase ÷ Original Number × 100.

 

So for horizontal 640 = 2560 - 1920

% = (640 / 1920) x 100 = 33%

 

So for vertical: 360 = 1440-1080

% = (360 / 1080) x 100 = 33%

 

So both horizontal and vertical pixels counts increase by 33% for going from 1920x1080 to 2560x1440.

So, egro, you need a mouse sensitivity (DPI) increase of 33% to keep the exact same sensitivity without having to change in-game sensitivity.

 

So if you had 1600 dpi, 1600 x 33% is 528. (33% of 1600 is 528), so 1600 + 528 is 2128.

So either 2100 or 2150 DPI would get you about back to where you were before, not 100% exactly but close enough.  Tiny 1.75% overshoot at 2150 and -1.75% at 2100.

 

This becomes far more complicated if you change aspect ratios!

Then you would need mouse software that would let you set X and Y axis DPI separately, and if not, you would have to go through the game.
