Got a custom 27 i7 iMac. One big issue.

looks like this has been happening for a while now

well, I just organised a replacement for my 2010 i7. This kind of backlight bleed/glow is not acceptable (to me at least) ... see pics below I just took.

if the second one i get is the same as this I will have to get refund. shame. its very fast! :(

Wow!! That is such a shame. Pretty much identical to mine. Can someone who doesn't have that problem actually take a pic and post it?

Very fast they are. The only game that can't play well at native res would be bad company 2. Plays great at 1920x1080 though, I blame that on crappy programming though.
 
exactly. wonder if we got a bad batch or this is across the board :confused: Save us going thru replacements!

people on this post say theirs are flawless.. https://forums.macrumors.com/threads/985619/

be interesting if they could take some pics with 100% black background (no other windows open) and compare to ours

To be honest, I think every iMac has the back-light bleeding in some degree due to IPS technology. But Come on , just give me an acceptable one , can you? APPLE
 
here are a few poor quality pics from my 2009 iMac week 47 iirc.

Well i got a phone call this morning from a support tech in Texas...He convinced me to send the machine back to Apple because the Apple engineers want to examine my unit.

So now I have to backup 40 gigs of....
-----------------------

First, good luck with the new one. I think that is better than replacing the screen since once you open it you run the risk of getting dust inside any dust behind the glass could drive you crazy.

Second, if you have a spare drive then I suggest you clone what you have using something like Carbon Copy Cloner. You do not need a 2TB drive to clone a 2TB drive, you just need a drive a little bigger than the data you are backing up. I do this all the time. This will make it very simple to restore when you new iMac arrives.

My 2009 iMac is perfect and I would never accept a poor screen since it is used for image editing and must be perfectly calibrated for color and brightness, which I do every month or two.

Good luck
 
not really acceptable for the price of the new imacs! I am coming from a Samsung 275t and when the background is black on that, there is no sign of blotchy backlight.

So maybe my expectations are a little high.. but I 'upgraded' thinking IPS was supposed to enhance image quality!

Lucky i haven't put the samsung up for sale yet. Have a feeling ill be needing it for a mac pro sometime in the near future
 
if you want real black get a plasma .... You won't need to use time machine anymore either. Your desktop will be saved to your screen perpetually :)

HOLY ****! Apple discussions just removed my post about my iMac issue.

I mean sure.. perhaps I shouldn't have titled it "Don't get a new 2010 27inch iMac", but still.. This display obviously has some serious issues that are a huge problem..

What a bunch of Nazi's!!

Apple makes many trade off with specs. It seems the trade off here is the IPS doesn't look so great on black images with mid-to-high brightness. I think your choices are to get something else or adjust your brightness and vertical viewing angle.

I asked you earlier but you either ignored or overlooked my question. Why not have Apple just replace the whole computer rather than just the screen, especially since you just bought it?

Well I have a windows partition a mac partition, and software installed on multiple drives between the SSD and 2TB storage drive. Does this software handle all drives and partitions at once? I will definitely check that software out then.

Looks fine with black images, it's just the unit other people and myself have are not legit. From other posts on this site, there are people who have new 27inch iMacs with perfect displays. So I have hope in the end. I do Visual effects for a living and even though I don't need a perfect display at home, it's nice to have the option to get nice looking renders where I can judge my lighting. Most people wouldn't be as picky, but this is one of the big issue for me. Looking at other posts, it seems you can have a new iMac display without screen issues.. I just have no idea how many times I have to return an iMac to get the right one.

It seems that this is an issue with IPS glow, a problem that is not isolated to Apple alone. This kind of 'glowing' effect can be seen in almost all IPS displays.

I think you are wrong. There are people who have 27inch Imacs without bleeding light issues such as mine. What world are you living on?

Example:
"No CountlovE, I don't have any screen bleeding issues. I actually read your original post a little bit ago, and was concerned so I did some tests, but experienced none of your symptoms."

One thing I hate is misinformation.

I just watched that video. Most of IPS glow from those monitors is actually blurred reflection coming off the matte surface of the screens. It is changing based of the incidence angle of camera to flat surface of the screen. The guy should have done his test in a dark room without lights or windows behind him.

Looking strait forward I shouldn't see this issue on the iMac screen.

I have new Dell IPS monitors at work, you do not find anything like the iMac I currently have.

I think the reason my iMac has this is from improper install of the screen. Since it is a custom build They might be flexing the screen causing the surface to bend ever so slightly. Now if you are building iMacs pulling the screen out twice. Once for the main build, and 2nd for the custom order, there might be more stress on the screen causing this to happen.
I am no Apple Engineer but I think is might be the reason why a lot of people are having this problem.
 
This youtube video shows IPS glow as well. But when you look at it 'square on' there is no glow. You only start to see glow from side angles, which is fine

What countlove and myself are seeing is a distracting amount of grey glow when looking front on. If my imac looked like the one in this video i would be very happy!

I think dagomike made a very good point. Possibly there is a trade off with the specs by Apple, and in iMac's case the IPS "doesn't look great on so great on black images with mid-to-high brightness". Im getting a replacment, but have a strong feeling the glow will be the same and ill make my choices then.

Is that comment with or without accompanying photographs? Some people simply don't care to set up their background, pump up their brightness -- or even are the kind that notice -- before posting that they have no issues.

IPS glow vs. backlight bleed


Does the light disappear as you move your head around relative to the screen? I think you're going to see light on an IPS panel with a pitch black background.

x2. This is normal. All of the 9 27" iMac's I've owned exhibited this. It's an inherent issue with IPS displays that could have been avoided if Apple chose to use a polarizer on the screen, but they chose not to.

Exactly. Has anyone actually seen photos of a 'perfect' 27" imac display yet? It's too easy to sit in a well lit room with a nice scenic wallpaper on your desktop and say "mine's perfect!"
