Posted October 17, 2018 Hey! My XB271HU has a small coil whine (buzzing) sound. It's not audible unless you put your ears very close to the monitor (on the area where the GSync processor is), but I'm wondering if it's in any way dangerous? I don't care at all about the noise, it's inaudible when further than 30 cm, but I'd like to know if it's okay/dangerous. I know coil whine isn't dangerous for GPU/PSUs, is it also the case for monitors? Thanks Link to comment Share on other sites More sharing options...

Posted October 17, 2018 It might be a fan in the back to cool components. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted October 17, 2018 possible, but coil whine isnt dangerous. It's just the metal (usually copper) coils in the inductors vibrating.

Posted October 17, 2018 Author I doubt it's a fan, it's probably just coil whine. I asked this question because I don't know too much about coil whine in monitors, so I didn't know if it was normal or not for monitors:p Link to comment Share on other sites More sharing options...

But is not dangerous. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
