Primay monitor starts turning off and back on when I turn secondary monitor

Hi, so if I turn on my secondary monitor, my primary monitor will start turning off (~5s) and turns back on. It seems like it only happens when I am moving my mouse and sometimes while I am typing.

I am on KDE Plasma, nvidia gpu x11.

I don’t really know how to look this up, so sorry if there are many posts about this issue already.


Update: If anyone also happens to have this issue, seems like the only option is to set the refresh rate of the monitors to be the same. So in my case my primary is 144 and secondary is 60 so I had to set it to 144, which is fine I guess because moving windows etc is at 60hz either way when both monitors are on
