It’s very easy to tell the difference when you see them in person. I have a 60Hz monitor and a 144Hz monitor on the same PC and you can drag a window across the desktop from one to the other and the lack of animation frames in the movement going from 144 to 60 makes the movement look choppy on the slower one. In games, the animation becomes smooth to the point of being lifelike and visually vibrant when your framerate is able to go up to 90 to 100 or more FPS
