– Can anyone explain the difference between computer display “hertz”, “refresh rate” and how it corresponds to “FPS”?

I really should know this, but I never really “groked” the concepts as they interrelate.

Thanks for taking the time.

Hertz is a generic unit of something’s frequency, or how often it goes back and forth. If you stomp your foot 1 time/second, you will have a foot stomping frequency of 1 Hz.

A refresh rate of a monitor is how many times your monitor draws a new image in a second. 60 Hz monitors draw 60 images a second, 120 Hz makes 120 images a second, and so on.

Fps is how many times your computer refreshes what it sends to the monitor.

This means that both your monitor and your computer can be a bottleneck on the smoothness of your gameplay, because if you have 144fps going from your computer, but a 60 Hz monitor, your monitor will recieve a different image, but you’ll still only see 60 images a second. But the same is true the other way. If you have a 144 Hz monitor, but are playing a game at 30 fps, well it doesn’t matter how many times the screen draws a new image, if that image is still the same picture. It’d be like shooting slow motion video of grass growing.
