Monitors flickering on wake and turning off randomly

Hi there, I bought the USB-C 4K a few months ago, which I really like and I’m using it with two monitors connected to my macbook pro 2018.
However I very often face a flickering problem on laptop wake and also sometimes a kind of static (?) which only last a few seconds, along with my right monitor that sometimes doesn’t turn on.
I have to unplug the device multiple times to fix it but it kind of painful.
Also sometimes all my monitors also turn black for a few seconds before going back to normal, and that can happen multiple times during the day…

Any help would be appreciated
