Why does the signal on the monitor turn off?

Question

Monitors

Hello! I bought an hdmi monitor specifically for giving, connected it to a laptop via a mini hdmi adapter ... everything is ok, after a couple of hours the signal began to disappear ... it disappears (dark screen) and after a second a picture appears with the inscription "source: hdmi" ... and it blinks so chaotically, it can blink a couple of times in 10 minutes, or maybe so often that it is unrealistic to work.
The light bulb in the room does not blink (like if welding works for someone), although it is led, maybe it should not.

I noticed if you turn off the laptop from the outlet and it runs on battery, then the blinking absolutely disappears. I googled this problem, they advised me to distribute the power to the laptop and the monitor to different sockets - I smashed it completely to different ones - it stopped .... very rarely, once an hour. Time passed ... and again it began to blink, even in divorced sockets. Turn off the laptop - everything is ok. Tested at home - everything is fine. I don't understand electrics, maybe the heaters are turned on and the voltage is low? What can be done here? Voltage stabilizer or what can help?

Thanks

Good day, when I turn on the refrigerator, the monitor also turns off for a couple of seconds, I think you need to look in this direction
