Some Apple Studio Display owners have taken to online forums to complain that their monitors make a high-pitched buzzing sound that appears to be emanating from the top of the screen or behind it, and may be being caused by electrical interference.
There are complaints on
Twitter,
Reddit and the
Apple Support Community dating back to June, and more recently on the
MacRumors forums, about the issue, which is variously described as an "electrical buzzing" and "constant ringing" that is "loud," "high-pitched," and "very annoying."
Several owners have found that the sound is not fan-related and only happens when a MacBook Pro or iPad is plugged into the Studio Display. Some have also noted that the noise can vary in intensity and pitch depending on the time of day, suggesting an electrical shielding issue may be the cause of the fault.
From Apple Support Community member
Ryan Roberts:
Some users have suggested the Apple Studio Display picks up interference from electric car chargers. In the case of
MacRumors reader
Indominus, they tracked the source of the interference back to Lutron Caseta light dimmers that are installed in their house.
MacRumors reader
uller6 relayed a similar experience:
Other users say they have tried electrical power filters to resolve the issue but to no avail, and some have received one or more replacement units from Apple that were similarly affected.
It's not clear how widespread the issue is, but Apple appears to be aware of the problem affecting some Studio Display owners, although a solution has not yet been found. It's worth noting that this is a separate Studio Display issue to the
widespread speaker problem that Apple eventually
fixed with a firmware update. Have you found the display to be over-sensitive to electrical interference? Let us know in the comments.
