  • Electric noise coming from my monitor (without speaker)

Hello

I am facing a problem with my monitor. When the screen is on, it starts making electric noises, but when it's off and still connected the power source, it doesn't make any sound. It's only making sounds when my screen is on.

PS: It's a used monitor and it doesn't have any speakers and I tried different power cables but I'm still having the same problem.
It is called coil whine and it s normal, probably coming from the power supply

Is it safe to connect it to my laptop?
