DPI and screen resolution

post #1 of 21
Thread Starter 
NO CS PLEASE, SC2 only


i searched for some info on this but as with alot of forums people seem to debate questions of their own

i heard that the higher the resolution the higher your dpi needs to be to compensate for it

could someone fully explain this to me because i am the MOST OCD mouse user and i cant even use my computer lately for lack of a precise mouse thats at the right speed


edit- for the record i use 1k dpi but i just want to know the relation of dpi and screen resolution

i was hoping that with higher resolution the higher dpi settings would actually be slower thus making a deathadders 1800 dpi sweet spot more closely resemble my usual 1k-1200 dpi


also i play sc2 so no CS refs lol the sc2 sens is actually windows sens

I don't understand why anyone needs a really high DPI. My mouse goes up to 5700 DPI. But I have never gone above 2000. It just gets so fast you can't even control it. What's the point?

I have memorized the formula.

resolution width * pi / (cpi*tan(FOV/2)) = minimum inches /360 required.

There is no point unless you're dealing with a screen as large as a football field or something.

Doing it wrong. It's like this

1: Raise DPI
2: Lower in game sensitivity
3: = more accurate mouse


You can do this until the resolution bottleneck kicks in


I use 800 most of the time because I'm too lazy to change it and I keep my mouse at low speed.

This will calculate useful DPI per resolution width at a given sensitivity. The "in-game" sensitivity is the same as games like CS 1.6 / CS:S / COD4/MW/BO (from console)


Example for me:

I use my Zowie EC2 @ 500DPI, 1.8 In Game (I have been playing FPS games like CS1.6 since 1999/2000 so Low Sens, Lower DPI, 6/11 Windows is the way I always go. (prob ~ 18 inches per 360)

At 1920 pixels wide, and that sensitivity, the useful DPI is only 331.

TBH anything over 1000 DPI is mostly useless even for high sens players.


@ 1000DPI, 6/11 windows, 2.5 in game @ 1920px -> useful dpi is only 921 DPI

Unless you literally like doing a 360 my moving your mouse 1/2 an inch (in which case i guarantee you will never be good at an FPS game.) anything over 1000 DPI or so is likely overkill.

Plug in your numbers and see what you get.


PS. I am just as OCD as you and doubt i will ever find, "perfect"

Is the FOV in that calculator vertical or horizontal FOV?

Anyhow, at 2048 wide pixels, in source, at sensitivity 1.52, at FOV 90, I only need 420DPI. According to that...

I believe it it horizontal, not the strange vertical conversion you need for games like BC2.
