Samsung Viewfinity S9 - Coil Whine - Sound Issue

[Canberk]

I recently bought a Samsung Viewfinity S9. I’m using it with my MacBook Air M3, connecting the MacBook via the Thunderbolt 4 cable that came with the monitor.

However, I have an issue with an electrical noise (probably coil whine) coming from the back. This problem occurs when I connect the monitor to the MacBook—a slight buzzing sound appears.

There’s no noise when the mac is not connected or when it’s in main interface of the monitor or in settings interface. The sound changes when I connect or disconnect the camera that came with the monitor. The sound changes when I remove the camera, and it changes again when I plug it back in.

I’m not sure if that sound is normal or not. Because, It’s very quiet, but in a silent room, it’s quite disturbing.

Is there anyone having the same sound issue with the Samsung monitors? Do you think it is related to thunderbolt cable. Should i but a new cable or should i use miniDP port?

im having the same issues. 

i've had a samsung technician replace a board already but the issue has come back about a month later. 

has varying levels of whine, using with both a mac mini m2 pro, and a windows laptop. doesn't happen when using monitors inbuilt OS.

just about to contact support for a more suitable solution.
