Hey, I swear this was asked before but.... I was wondering about pixel density/PPI and muscle memory/sensitivity. (skip to TL;DR if you know all about this) Say for example I have two monitors - they are the same size (~24" diagonal) - but one is 1920x1080 and the other is 1280x720. The 1080 has a PPI of ~92 and the 720 has a PPI of ~61 (http://dpi.lv). Now say I was to move my mouse across both screens (desktop). The 1080 monitor would be much slower than the 720 monitor due to the difference in the number of pixels. But if you think about it, the mouse sensitivity doesn't actually change, so long as you move the monitor away from you so that it is the same size as the phone - since they are the same resolution. For another example, say I have a phone and a monitor. Instead of having different resolutions they both have the same resolution. The size of the monitor is still ~24" but the phone is much smaller at ~5". Now if I were to move my "mouse" across both screens the mouse would move much slower on the phone but much faster on the monitor due to the difference in the pixel density. But if you think about it, the mouse sensitivity doesn't actually change, so long as you move the 1080 monitor closer to you so that it is the same pixel density as the 720 monitor. I know that pixel density doesn't really matter because it scales bigger or smaller depending on how far away you are. But the tricky part for me to wrap my head around is if I DON'T move the screens to compensate for pixel density. Say for example I have the same monitor resolution, with the same size - therefore the same pixel density. If I move one screen away from me, the pixel density will be much greater. Since they are the same monitor but they are at different distances from me, what bearing does the change in pixel density have on my sensitivity? TL;DR I thought about all this because I'd like to get a gaming monitor that sits further away from me, but not sure how the change in distance will affect my muscle memory/sensitivity.
