So, the other day, I was messing around with my mouse settings, you know, the usual stuff. I got into this whole DPI thing and started wondering about 400 DPI versus 800 DPI.
I started by digging around a little. Apparently, DPI stands for “dots per inch.” Basically, it’s how many increments your mouse can move in an inch. So, 400 DPI means there are 400 of these little increments in every inch you move the mouse.

First, I set my mouse to 400 DPI. I hopped into a game to see how it felt. It was pretty smooth, honestly. I could move my mouse around, and it felt really controlled, especially when I was trying to aim precisely in the game. Then I tried 800dpi, and I’m trying to see any difference between these two settings. Not too much of a difference, but I could see the mouse move slightly faster. I could feel the smooth mouse movements with 800 DPI, but I’m trying to see any advantage over 400 DPI. I guess it’s personal preference or something.
I also read somewhere that 400 DPI picks up less information than 800 DPI. One guy even said it could be more forgiving. But then another person said that with modern mice, it doesn’t really matter much between these two settings. They are pretty much the same.
Then I messed around with in-game sensitivity settings. I found out that 800 DPI with 0.5 in-game sensitivity is kind of like 400 DPI with 1 sensitivity. But people say 800 DPI at 0.5 is better because it’s higher resolution and has lower input lag.
Here’s what I tried:
- 400 DPI: Played a game, felt smooth and controlled.
- 800 DPI: Felt a little faster and pretty much the same smoothness as 400 DPI.
- 800 DPI with 0.5 in-game sensitivity: Supposed to be better than 400 DPI because of higher resolution and lower input lag, but I couldn’t tell the difference too much.
I even read something about higher resolutions like 1440p or 2160p. Some folks say that higher DPI feels much better on those screens because there are more pixels. I don’t have one of those fancy monitors, so I couldn’t test that out.
My Conclusion
After all this, I’m still not sure if there’s a huge difference between 400 and 800 DPI. Maybe it’s just one of those things where you have to try both and see what you like better. I guess I’ll just stick with what I’m used to for now. Maybe I’ll try 800 DPI for a longer time, who knows.
