For a few months, the person in charge of the Studio Display monitor project must not have slept very well. Apple's brand new external monitor is having many incidences of malfunctions. Too many for a monitor that costs 1.779 Euros.
So once the problems of the integrated webcam have been overcome, it seems that the complaints of some users who hear a rather annoying slight buzzing when the monitor is on continue. Inconceivable considering the value of the screen. Let's see what could be the reasons for this sound...
Ever since Apple released its new external Studio Display a few months ago, some Studio Display users have been complaining about an annoying buzzing noise coming from inside the screen. Something inconceivable in a monitor that costs 1.779 Euros per wing.
Complaints posted on various tech forums explain that on some units of Apple's Studio Display, there is a slight (but annoying) humming sound coming from the display casing. And it seems that said sound increases when a MacBook is connected to it. rare rare
Apple is investigating the issue, but has not found a solution yet. It may be a hardware failure, since if it were software, those from Cupertino would have already solved it with an update. Let's look at the possible causes.
The fans
When a MacBook Pro is connected to the Studio Display, the Thunderbolt connection also provides charging power. As a result, the monitor's fans start spinning to keep the internal power unit healthy, which can cause a high-pitched hum.
Putting the laptop to sleep or turning it off will not make the buzzing sound go away. The fans only stop when you unplug the laptop from the screen. If you have a Thunderbolt dock, try using it to charge your MacBook while the Studio display is connected to the dock. This avoids direct charging.
A bug in the software
It could be that the Studio Display software has something wrong, causing the blissful buzz. But it is unlikely, since Apple would have detected and fixed it in a device update, as it did with the problems of the integrated camera.
defective units
An unlikely cause is that if you hear the buzzing in your monitor, you have been dealt a faulty unit with some manufacturing fault. It's as simple as going to Apple and having it replaced with another unit, see if you have more luck and stop hearing that sound.
Power supply
Some of the affected users indicate that the buzzing is coming from the left side of the screen, where the internal power supply is located. So it could be that said component vibrated more than normal, touching with some other part or the same casing, thus causing the annoying buzz.
electrical interference
Some users explain that the buzzing occurs when some certain electrical appliances are working near the monitor. It could be electrical interference from the electrical circuit of the house, from air conditioning, electric car chargers, etc. If that is the cause, then the device has an electrical shielding problem.
The fact is that the Studio Display has been on the market for a few months now, and the company has not yet found a solution to the annoying buzz. We'll see how things turn out...
