Changing from 1080 to 1440, help with DPI changing...

[3sword]

I'm taking the leap and going from my old 1080p BenQ to a ASUS 1440p monitor. Since the resolution will be changing doesn't that directly affect my DPI? So it would be 1440/1080 = 1.33 which means I would have to do 800 DPI*1.33 = 1067 DPI as my 1440p DPI. My mouse only does increments of 400 DPI therefore I can only go up to 1200 which is too high. Could anyone help me sort this out as when I do the calculator, which I think I'm doing correctly, it only changes my ADS sens slightly. Does monitor distance coefficient play a part in the change? Pretty confused at the minute, thanks!

For most 3D games nothing changes when you change resolution but keep the same aspect ratio. The FOV and 360 distance will be the same. There are a couple of games that are directly affected by resolution, but that's not normal.

For Windows however you probably want to change DPI if the old one feels too slow. And if you want to play with this new DPI you also need to re-calculate the sensitivity for your games.

The calculator will scale the sensitivity according to the monitor size if you input two different ones. Some prefer this when changing monitor size, but this is purely based on size and not resolution. This does not work for 360 distance obviously as it stays the same, which is why you only get a difference for the ADS in your example. To also scale hipfire you need to change it to MDV 133% as well. This will change the calculated hipfire sensitivity, and all ADS will be the same as before since they scale to the now changed hipfire.
