I do hear the buzz when I lower the brightness under 60-65%. Can you guys check yours? I think it's normal, and I certainly would never have the brightness that low but I want to make sure it's not just me.
 
Mine is coming Thursday. I'm so happy. Only 2 weeks late. Cleaned up the desk yesterday in anticpation. I'm looking forward to my problem free machine (positive thinking).
 
Buzzing screens

Guys, to be honest I think this is something to do with the power needed to make such a large screen work. I have a 50" plamsa tv (not the same I know) but that does buzz a bit, and as you adjust the brightness the buzzing changes too. I have it set now and its not noticeable at all.

As previously mentioned here - if you need to put you ear to the iMac to hear a buzz - its a non issue - its probably impossible to remove all electrical buzz on a screen so big and bright as the 27" iMac.
 
27" i7, 8GB RAM, 1TB drive

Ordered: 1/28
Original expected ship date: 2/19
Actual ship date: 2/4
Original expected delivery date: 2/24
Scheduled delivery date: 2/9

Serial number says it is a week 6 machine. Hoping for the best and will update when it arrives.

Received mine today. No problems that I can see. If there's any yellow on my screen, it's not bad enough for me to notice. No noises, no flickering. It does seem to run hotter than the 24" iMac that it is replacing did, but I'm guessing that is to be expected and it is nothing that seems unusually high.
 
Got some good news today, kinda...

Shipped Feb. 2 (ordered Jan. 22)

ETA for arrival Feb. 6. (does not seem to make much sense... 4 days for shipping?)

3 days late so far... But at lease it's shipped.
 
Ok I picked up my iMac this afternoon but I had some studying to do. I set everything up and the screen is the best I've had so far. It's a my 4th one. I'm currently installing programs on it, posting from my MBP.

Week 6 i7. I notice the bottom left rectangle is a different shade, but that's only in the photo.

What number is your iMac from the assembly line of week 6? Mine is 517. It's in anchorage right now.

I hear a slight buzz / humming when I lower the brightness. I have to get real close to hear it. Since my room is never really quite I am not that worried about it.

Thanks for your update Joey, I'm not worried about it either - it seems to be a common non issue.
 
All iMacs buzz. Period. The end. If it's really obvious in a quiet room, there MAY be something wrong with it. But they do all buzz. Some people have very sensitive hearing, though, which is why it can be an issue.
 
rather the buzz then the high pitch noise. i just can't stand those hich pitch noises. My actual monitor an LG ( :confused: ) does a buzz to lolol so i'm getting used to it
 
I had ordered my i7 on the 1st of Feb-- finally started shipping. It has an estimated delivery date of the 15th.

I have the 1107th unit built in week 7.

One important thing of note: the serial number decoder thing labels this screen as a TFT LED backlit, and not IPS. Is this any different from other people's iMacs before? Maybe apple changed the IPS panels to TFT because they acknowledged the problem was the IPS technology that LG implemented?

Your confused bro, it is a TFT LCD IPS panel. TFT just refers to "thin film transistor" which is just a variant of LCD display. TFT just refers to the type of LCD panel.
Which TFT's are the most prevalent LCD's in production.There are variants of TFT Displays with IPS being the best of the lot.

Ah ok. I actually remember now what I was confusing TFT with. I was confusing TFT with TN, as they both started with T.

My i7 also shipped today... 1141th in week 7. Let's see if the screen is any better...
 
My iMac has been stuck in Alaska for the past 24 hours. I don't it has said in transit for the past 24 hours. I don't know if i will get it tomorrow?????
 
So it's at my local Fedex Facility. I don't know when it's going to go out for delivery but is there a way I can go and pick it up even before they try and deliver???
 
If it's not on the truck then I don't see why not. Give them a call.


It is out for delivery. I am so excited!!!!. Can't wait!!!! I have everything set up and the 4 extra gb of ram ready to install. Will tell you know about the screen and buzzing as soon as i get it!!! Once again it is a week 6 517th i7!!!!

Mine's on the truck too. As soon as I get the email that it's been delivered I'm going to get a case of "I have to go home sick". Plus it's a 4 day weekend (furlough + holiday) so I'll have plenty of time for the new toy.

My iMac is currently sitting in the UK distribution centre, which I suppose is in Hinkley. Still says my delivery date is 18th February, pretty sure it won't take a week to get across the Irish sea. But the weather could be out to get me.
