60 hz is the standard for an LCD monitor, so pretty much all are 60 hz /refresh rate/. It's not as in the old times of CRT monitors, where the picture were "scanned" at a given speed and this /then vertical/ refresh rate stand for the speed and frequency the picture was built on the screen. Now on LCDs the picture is refreshed more like all at once and it's kept "alive" /meaning like valves open/ until the next refresh. So 60 hz is universal and it's OK, no matter if it's gaming or reading books /gaming doesn't get special treatment/.
Hope this helps.
It means it responds in 5ms or 2 ms after a value on a "valve" /pixel/ is changed. 5ms stands for 1/200 sec and it's much faster as 1/60 sec, so they both will switch fast enough to keep up with a 60hz refresh rate. It's like a characteristic of the "inertia" of the monitor. And actually below some 8-10 ms is not that much important /except for advertisers/.
+ this 2 ms or 5ms is for Gray-to-Gray switch, meaning both the initial state and the resulting state are somewhere arround the middle values, it,s much higher for a full Black-to-White change, and even higher /as I know/ for White-to-Black - up to several times. But even then it's enough to keep up with 60 hz refresh rate.
