Weird sounds coming from monitor speakers

ShadeOak

Hi so I got this curved screen model ED273 (LED BACKLIGHT)

I don't use the sound on it but sometimes there are buzzing sounds coming out of it.
I tried setting the audio level to 0 in the monitor menu but it still does it.
I think its some kind of interference with some radio waves or something.
Its not really that bad but I was wondering if there would be a way to completely deactivate/disconnect the speakers to make it go away.

Typically that type of issue can be traced back to the power, either the outlet isn't properly grounded, there is a ground loop among multiple devices connected to the same circuit or there's another device on the circuit introducing noise. Can you trace it to something like a vacuum cleaner, air conditioner, refrigerator or the like? Is your monitor connected to a surge arrestor or UPS? How about the computer itself?

everything computer related is plugged into a single powerbar. I'll try to plug the monitor directly into the wall and see if it goes away

Please let us know if it helps, or if it doesn't.

I have the same issue with a radio signal being picked up from my Acer XF270H monitor. I looked in the settings, switched the DisplayPort to an HDMI, plugged it into another outlet, switched headphone from Bluetooth to regular USB, turned off Bluetooth,....but no luck. Has anyone else found the trick to stopping the monitor from picking up radio signal? I have a complicated setup,...using OBS Studio to stream and OBS audio to my headphones (the stream isn't started, just in preview mode), I'm using a USB mic (XLR to converter box to computer's USB). If I unplug the USBC connection from my monitor to the computer the signal stops (although if I unplug the XLR to the converter box, the signal also stops). Thank you for any advice.

See if you can find some cables with a full shield, connected to shield ground only at one end. They will be much less susceptible to picking up interference. It sounds like your cables either have their shield connected at both ends (causing a ground loop) or (more likely) are unshielded.
