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.

I'm seeing this too - I didnt used to tho - maybe its related to a recent update?

Update on my condition;

I sent the product to Samsung for repair, but the issue remained unresolved, so I requested a replacement. Now, I’ve received a new monitor, and the same sound persists. When I remove the camera, the noise becomes slightly more bearable, so I’m forced to use it without the camera. 

It’s interesting that the issue doesn’t occur when using the monitor’s own interface and only happens when connected to the computer.

I’ve tried both the 1405 and the latest 2000 firmware versions, but the issue remains the same. I’m not sure how to resolve this problem.

Does Samsung expect us to just get used to this sound, or am I just unlucky with faulty products? I’m not sure what’s going on.

It looks like it is a common problem. Is there anyone who can help us from Samsung Team @Samsung_Moderator ?

I have tried 3 different Viewfinity s9 monitors now and exactly the same coil whine when I hook it up to MacBook Pro with the thunderbolt usb-c with all three of them. Stops the moment I disconnect the cable keeping the monitor powered-on, really annoying. Returning the 3rd one and I am done with this.

Having exactly the same problem. When connecting anything to an USB C port (camera) it becomes very loud. Samsung please help!!!!

Same issue, brand new monitor when connected to macbook m3 pro gives coil whine,  when removing camera and other devices the frequency changes. Does this happen to everyone? Should i return it or request a replacement?

I got my motherboard replaced by Samsung. Now it’s quiet. Let’s see how long that will last?
