Code:
360° * 2.54 (inch to cm)
----------------------------------------- = 11.55 cm/360
1800 (DPI) * 0.022 (yaw pitch) * 2 (sens)
I think this is absolute minimum for consistent quick and precise aiming in shooters. With sensitivity 2 there won't be noticeable "skipping" even at very high resolutions, 1920×1080 should be fine.
While 1800 is already usable at very high resolutions it tends to be a bit too slow, in my opinion, at "very high resolutions" at default sensitivity settings, in my case 5400x1920. So I personally would not state any definite number as "thats good enough". The 1800 dpi would be probably adequate if one is playing on single screen however, multiple screens are no longer strictly negligible portion of systems that are used for gaming. Here is the current Steam hardware survey:
http://store.steampowered.com/hwsurvey/ - umm .. it seems that they have some hiccup in the system atm, anyway, when they get ygheir data back visible and if you look at the "primary display" section in there you see that good number of systems have their main screen at higher resolution than possible with a single screen so they are using either Eyefinity or Surround setups.
