Mouse sensitivity and Resolution

[DahPython]

I recently just switched to 1440p from 1080p. I was wondering if my mouse sensitivity and aiming will be affected. If it does, is there a way to find out how to raise my mouse sensitivity to match how it was for 1080p to now 1440p?

It'll be affected on the desktop and in 2D games, but in 3D games your sensitivity will stay the same.

Well from a purely mathematical perspective, you'd raise the sensitivity by the same % as the pixel count.

 

BUT....

 

If you have a higher DPI setting available, I'd use that first.  DPI increase (if possible/available) is nearly always preferable to increasing sensitivity or g-load.

I cant say I have really noticed a sensitivity difference between resolutions excepts obviously the cursor size. Full disclosure currently running two 4k 32" displays.
