2017 iMac 27" 5k - BUZZ ELECTIC NOISE - URGENT

iMac - MacRumors Forums - forums.macrumors.com
Hi,

I bought an iMac 27" 5k (2017 model of course) and I received it 10 days ago.

Since 3-4 days ago I noticed after just some minutes it makes a kind of "electric noise" when the monitor is "used", I mean when I do something on the screen, even for simple tasks: scrolling, resize a folder, watching video etc. Especially when the brightness is at max level.

I am not talking about fan, I talk about the electric buzz you can hear in the video I made.

This noise is NOT loud, but it's possible to hear it, I can't work well with it and especially I think it may become a huge problem near the future.

My questions are:

- Is it normal? does your iMac doing the same electric noise when you do something on the screen and brightness at max level?

- WHAT SHOULD I DO? I received it 10 days ago. Should I ask for a complete refund to Apple, and buy a new one?

Please check the video: of course I increased the audio so you can hear the buzz.

THANK YOU SO MUCH.
