OK

pu2. In general, 60 Hz is enough to watch the Internet or videos, and in the case of games, quick screen change is often necessary, so it is better if the hz is higher

OK

pu3. 60Hz means 60 screens per second and 144Hz means 144 screens per second
As for the video, the higher the Hz, the smoother the screen feels
