Internet connection breaks when connecting to video projector

I have a problem with internet connection. When I connect my video pojector to the laptop via HDMI and switch for mirror display or other external display views, I lose the internet connection. I have no issues with another external monitor I daily use and I had no issues with the projector too until today. I have ubuntu 18.04 This is the dmesg output error:
