How I can check my current refresh rate of my display in Ubuntu 18.04?

Asked by Piotr on 2021-05-31

Dear Community,

How I can check in easy way my current refresh rate of my display in Ubuntu 18.04 (bionic family system)? Must I use xrandr or it is graphic way (GUI) to look this? If not what is the easy and safe way to check this by terminal?

Second question is if I have display with higher refresh rate than 60 Hz (for example 144 Hz) this will be work correctly in Ubuntu? This will be work great in games like Counter-Strike?

I hope that you will answer.

Thanks!

In my opinion the easiest way to see this information from Ubuntu side is using xrandr

Maybe your monitor has some kind of On-Screen-Display where you also can see that information.

xrandr is safe tool for monitor and graphic card? It can change firmware settings for monitor or graphic card ? In manual I can read that this is primitive tool. This little scary me.

Can you help with this problem?
