Is it placebo effect?

I used to play Val in a 21inch 75hz monitor and i always complained about how hard it was to see enemies and flick around. Yesterday, i bought a 24inch 144hz monitor and it literally feels like a different val, not because of the higher fresh rate, i played in 144hz befo, but its because of the bigger screen size, it feels like my enemies are literally giants instead of tiny little models in my old 21inch monitor.
Do you all think its placebo or theres that much of a difference between 24inch and 21inch monitors?

well 3 inches is a lot🙏

No its not placebo i have more accurate long flicks due to better peripheral vision on smaller monitors and better micro flicks on large monitors due to target size. I have aimlabs scores that i struggle to beat on certain monitors but are easy on others

Yeah definitely the screen size, when I got my monitor I literally started to aim a lot better and gained a few ranks in a few weeks
