Hello everyone

(to those who have received your retina imac)

can you give a report on your screen? I'm thinking about buying one but last time I bought an iMac (late 2012) the panels were terrible, I went through 5 of them to get a good one. The problems were image retention, edge bleed, and yellowing. Does any of your iMacs exhibit any of those symptoms? I heard all the panels are made by LG. So to be honest i'm a bit scare to jump in. Looking forward to your reports.

Thanks!

Edit: Make sure to run your iMac through these tests to make sure its fine.

These are the tests:

Retention tests: http://www.marco.org/rmbp-irtest.html

Yellow Screen: http://imac.squeaked.com/test.php

Screen bleed (make sure to make your browser full screen):http://jasonfarrell.com/misc/deadpixeltest.php?p=1

If your screen passes all these tests then you truly have a good screen.

Thanks again.

My Retina is very sweet.
Don't know why you are unsure about LG, I have 3 LG TV's and they are all as good as any I have seen

The screen is truly amazing. I haven't spent too much time on it yet, but it's really gorgeous. No image retention, bleeding or anything.

I don't know who manufactured mine. The fact that iFixit got a LG screen doesn't mean that they're all LGs. However, LG does make very good panels, it's just that the Mac community loves scaring themselves. My rMBP's panel is a LG and it's perfect.

Im going to post what i posted in another thread check it out:

"If you bought retina in the past or just regular screen manufactured by LG then you will truly understand why OP is worried. I am worried myself too since I want one. I bought a late 2012 imac (first thing imacs) when they first were announced. I had to go through 5 replacements to get one good screen and they were all made by LG. They had horrible horrible edge bleeding and screen retention. If you look at all the LG panels, (even their own series of monitor) they are very prone to have these issues. When it comes to retina, the Ipad air panels also have the spine effect where the left side darker than the rest of the screen. These problem still exist today, I Bought one and returned it, and if you dont believe me, go to your local apple store pick up one put a white screen and look at the left side you'll see what im talking about. Also lets not forget about the retina macbooks with all the screen yellowing and screen retention issues from the LG panels. I remember people going to the apple store getting replacements and opening a couple of them and making sure that they got a samsung panel because those are the good ones. Yes its a new technology, yes these panels could be higher tier but LG just hasn't been reliable in the past and there isn't a worse feeling than opening a new imac, noticing a crappy screen and seeing that hole in your bank account. I dont think it sits well with anyone. Only when you had these experiences is when you truly understand why someone would be worried about LG."

thats what im going to do see how many people actually have these issues, last time it was all over the place so hopefully this wont be as bad this time around, but who knows I lost all trust on LG.

Here are some examples from their newest panels:

and

Dave D's new LG monitor, this one is great example because he has multiple monitors showing black and the only one has edge bleed (look at the corners) is the LG:

I remember your screen problems. If you're happy with what you have today, I urge you for the sake of your sanity and happiness to wait a long time before embarking on the retina route :)

Thank you!

thats why im waiting to see before I order because I dont want to go through that ever again. At the same time.. I really want an upgrade really bad. Apple has been doing retina for a while now im hoping they got it down but im still worried about it because its a larger display.
 
edry, long time, no see!

:)

I have an RiMac on order, but I'm not going to be able to get time to mess with it for a week or so. But you can bet I'll be testing every facet of that screen.
 
Not sure why you'd be so paranoid, but I'm hoping mine has an LG screen as perfect as the one in my rMBP has been since day 1. A bad past experience does not a generalisation make. Also, my new LG 84" 4k TV isn't shabby either.

I hope so, too! I have faith that Apple did a good job, here, especially since they spent so long talking about the new screen tech. Time will tell, I suppose!
 
From first impressions, I can tell you a few things about the iMac 5k display with a somewhat naive sense of certainty:

The display is indeed gorgeous. No apparent ghosting, incredibly and noticeably detailed, and less edge vignette than I've seen on iMacs prior. From what I can tell, it runs at a smooth 60hz (even with scaled resolution) and has 32 bit color. Assuming there are no defects, these iMac 5k Displays are excellent. In that regard, I'm satisfied.

Lets hope so! Off topic: what's the deal with the gpu? I tried looking at the other threads and everything seems like a mess. Without going too deep into it what's going on with the gpu, is it just bad? Im not gaming im just doing heavy photoshop, Premiere Pro, After Effects and Davinci resolve. Is it not good for that stuff? care to explain?

could you run some of the test that I mentioned above, if you do so let me know how everything turns out.

Edry, there is no deal with the GPU. It's likely just not as fast as some of us hoped it would be in terms of gaming. With other stuff, it seems... fine? Very speedy. But then again, the 2012/2013 iMacs were no slouch either. I think you'll be pretty pleased with the new iMac based on first impressions.
 
I've seen and played with two 27" Retina iMac units at the Apple Store.

There is yellowing/temperature shift towards the bottom, but like with the prior 2012-2013 27" iMacs, they are subtle enough to not be noticeable with everyday usage.

I can't test backlight bleed or IPS glow because it's way too bright at the Apple Store. Assuming it's IPS, you're always going to get noticeable glow on corners, especially the top two on the iMac displays.

That yellowing is, quite often, viewing angles. Every iMac looks that way when standing above it. When seated a bit lower, it's almost unnoticeable. My current iMac is that way. The problem is, at the Apple Store, you're standing above it, so it will probably appear yellower toward the bottom.

Oh for heaven's sake, not this again. I don't want to see one zillion threads about "yellow tint" or "graying" or any more of that bull$h!te.

I suggest that you stick with what you have if you're happy with it.

if it bother you why did you even bothered coming here and commenting? I want to make sure I get my money's worth. If i buy a computer id expect it to be working 100%. If there are a lot of people with these problem go scream at apple for having poor quality control not the consumer. Is it bad I want to make sure that there isnt a problems? wow..
 
Of course there's not a problem with wanting to make sure there are no major issues with a new release. For example, I am absolutely ready to order a 5K iMac, but I'm waiting an extra week or so to see how things pan out with the GPU (which I'm sure is fine).

However, it is more than a little overboard when folks start inspecting every 1/4 inch with a microscope just looking for the slightest imperceivable imperfection. I vividly remember the intense crying that was going on with the supposed "yellow screen" issue that surfaced when I bought my last iMac. If there is a glaring problem, one should definitely be concerned. But folks were going completely overboard on that one. I remember one guy exchanging his iMac 5 times because he was "seeing" things the human eye can't even normally see. The whole thing was kind of ridiculous...

Apple makes great products and people should have reasonable expectations.

Its is ridiculous to look at every micron of the computer, and thats one thing. But screen retention, edge bleed and half a yellow screen is something that inhibits people from using the computer successfully. I work with photo, graphics and video so its CRUCIAL that my screen is perfect or as perfect as it can be since i need it for my work. Plus is not bad to ask for something that should be right to begin with. If you're stupidly looking at every micron then you're a jerk but this is not the case, at least for me.

When I bought my LG TV, the forum members for that TV were screaming about uneven lighting. I saw it on my set. Looked terrible......when it was on screen saver. Once an input was applied, it went deep black and was perfect. Yet everyone seemed up in arms about the backlight when NOT in use. Look for stuff, find stuff. There are credible complaints about displays (the new Kindle isn't looking very good), but sometimes you just need to look at a display and if you like it, stop there and enjoy.
