Blotchy display with yellow tint.

My 27" 2009 iMac i7 display has become extremely blotchy and has a yellowish-gray "horizon line" running across the bottom of the screen. I'm aware of the display issues with the first run of these machines, but was hoping mine squeaked by without these flaws. Apparently not. Any fixes out there or is it straight to the Genius Bar for me?

My iMac, which seems to be equally spec'd to your's just developed this same issue last week. I took it in on Saturday and I'm supposed to be picking it up this evening. Hopefully you were able to get yours taken care of, and hopefully mine looks just like new again when I pick it up tonight. I'd heard lots of comments about this defect occuring when I was shopping for mine, but thought I'd escaped it, then out of no where it just popped up more than a year later.

Replacing iPad Air with Yellow Tint?

Hello everyone, I recently received my iPad Air last week from Best Buy and it seems I have the yellow tint issue.
Can I just go to the genius bar and have them replace it or do I have to go to Best Buy?

Actually all LCD screens are constructed from multiple layers which are bonded together, so yes, the screens are "glued" together for want of a better description. There are many layers making up the screen, including the backlight/diffuser, two polarising layers with the actual liquid crystal sandwiched between them, for a lot of displays the touchscreen itself is another layer on top of that (on the iphone and ipad mini its built into the front layer of th eLCD, on the ipad 3 and 4 its a seperate piece of glass laminated onto the top of the LCD - i dont think anyone has sliced through an ipad air yet to find out how the lcdis constructed). with all of these layers - what do you think holds them together and stops them falling apart??? ifixit wont have mentioned this since you cant delaminate an LCD display without shattering the very thin glass layers off, they just treat the LCD display as a single unit.
And yes there was a well known issue with the iphone 4 where they were shipping the so fast the bonding agent hadnt fully cured, meaning that anywhere on the display it was slightly thicker, it gets slightly yellowish
for my own personal iphone 4, after a 6 week wait for it to finish drying, it was still yellow so they replaced it.
it is perfectly possible that in these ipads, the bonding agent holding the multuiple layers of the touchscreen together not finished curing

Nano 4 with yellow tint screen at top

Have iPod nano 4...has a yellow tint to screen toward top..have brightness turned up which makes it a bit better.
How do I fix this??

The warning triangle is indicating possible poor printing on that particular image.
Most smaller images(i.e. book size) need 300 DPI for sharp images void of aliasing.
The warning triangle is indicating that you have zoomed and cropped this image past the point of ~300 DPI and the final output my not be as sharp as it could be and you may see aliasing.
Scale the image back down, i.e. bring some more pixels back until the triangle disappears... or close to it...

Apple Cinema Display 30" with yellow tint: how to solve?

Hello all,
I just bought a second hand Apple Cinema Display 30" .
But I see white page seems to be more yellowish tint than my other ACD 30" which is more blueish..
Is there a solution to solve that problem ? Is there a software that can set the settings ?
Thank you

You need to get a video card the has the umph to push the monster. I believe there are a couple out there for PC's. Nvidia is one manufactuer that makes a video card capable of pushing the 30" to it's max res!!(which is frikkin sweet!)

Display with negative tint

I have a MacBook and the display is much different and an option that i cannot find on the settings. The display on my screen has a negative view to it. As if you were looking at a picture film. I have all the current updates on it, the hard drive is only months old. I don't know what is wrong with it, if a setting what changed that I can't find or if my computer is messing up? what do I do? Please help.
Thanks in advanced.

Open the Universal Access pane of System Preferences, click on the Seeing tab, turn off White on Black, and drag the Contrast slider all the way to the left.

Screen with yellow tint - 2nd gen

I just replaced a first gen with a 2nd gen ipod touch. The 2nd gen's screen is yellowish with washed out contrast. Is this a known issue? Will an Apple Store consider it for replacement? It's not completely unviewable, just harder to read.
thanks

we can't speak for your local Apple store. go to one and ASK.

Why some ipad 2 have yellow tinted screen? Can Apple give us an explanation?

It's so obvious.
Every ipad2 showed to us in the stores has cool screen.
Yet what we got have warm ones with yellow tint.
This also happens on iphone 4 and 4s.
Is it quality issues or something else.
Apple owe us an explanation.

Seeing as how Apple will have to answer your question, instead of posting it here on the user to user forum you really should post on it on the Apple feedback site,

Yellow tint PROBLEM FW+AI+PS

Hello,
I am having a serious problem with kuler panel in FW, AI, PS
and with search field in FW + AI.
http://www.designme.sk/junk/omg.png
Cant see the kuler colors as they should look like, because
they are covered with yellow tint (looks like 50% alpha).
This was happening on with my old graphics (geforce 8600gt),
but happens with new (radeon hd4670) one also. Latest drivers,
latest updates, lates everything.. So I reinstalled windows, sp3,
windows update, new drivers, clean CS4 install.. Same freakin
thing. Can anyone tell what is the problem here? I am using
download version cs4 design premium english.

@designme.sk,
I am curious... did you use calibrated device to help correct
color management problem in your monitor? If no, I recommend that
you should consider to invest in one of those nice
professional-quality calibrated device. In many case, having
corrected color profile set up in your monitor, then workflow
working with your project with "the right color profile" in right
approach, the right way of managing color management.
As you probably already know how important color management
is, so I don't have to go into that further.
Hope that helps.
Cheers, DWD

IPhone 5s yellow tint in camera roll

I got a new 5s over the holidays specifically because I wanted a better phone camera before our new baby comes. However, my phone takes REALLY yellow photos. Even when I try to color correct, they are significantly yellowed. I downloaded the Photoshop app, and the simple act of opening a photo in Photoshop fixes the yellow tint, even without applying any filters or color correction. Can anyone help? I'm happy to have at least a temporary solution, but having to consistently edit every photo I take with my phone seems redundant. Especially when this seems to be some issue with the camera or camera roll?

Ok, so I figured it out.... I must have selected a filter in my camera roll at some point, and it just kept taking pictures with that filter. I think it's REALLY dumb that the default isn't NO FILTER. Plus, there's no batch edit, so I've got over 100 photos with yellow tint that I have to fix one at a time. *sigh* Anyway, I thought I'd post the resolution for anyone else having the same problem I did who might be searching for an answer.

Yellow tinted display

Is anyone else still experiencing a yellow tinted display screen after "restoring" to 5A347?
I'm wondering if this problem is isolated to my phone, and it could be exchanged for a new one.

I just exchanged my 3g Black 16 gig iPhone due to a yellowish screen. My new replacement came with the (5A437) version. It is still a bit yellow but now the contrast is off making the text blurry and gray. I have another 3g white 16 gig with the (5A435) version which has no problems. The color is very rich and has deep blacks. I hope the is a way to correct this in the future. Upgrading the version does nothing. This is my 4th replacement phone and I am sick of making trips out to the Apple Store every week.

My refurbished iPhone 5 display has a yellow tint?

I got a replacement iPhone from AppleCare today, and I've got everything figured out with my new iPhone 5. When I was texting my friend, in messages I noticed the white background in the messages apphas a yellow tint to it. To make sure I wasn't seeing things or anything I got my iPhone 5 that I'm sending back to Apple and I compared both displays and the refurbished iPhone (I assume it's refurbished, there is little noticeable marks here and there) has a yellow tinted screen, and it's very noticeable, regardless on screen brightness.
Is this normal in refurbished iPhones, or any refurbished apple devices? Can I call Apple back and request a new replacement iPhone 5? The yellow tint is pretty annoying, and I have an iPad as well, so I can really see the tinted yellow display.

Is it new? I heard it was some minor problem with the adhesive glue on the iphone, and that it should go away in a couple of days/weeks?
If you're super concerned about it, you should go to the apple store and have them check it out.

IPhone 3Gs has a color temperature display is warmer, or yellow-tinted

All greetings!
My new iPhone 3Gs has a color temperature display is much warmer, or yellow-tinted compared to the my iPhone 3G.
It is a defect of my iPhone 3Gs?
Here you can see it: http://farm3.static.flickr.com/2415/2660565874_ef8a841a20.jpg

I recently bought a 3Gs and compared to my old 3G there's a hug difference! my 3Gs looks really yellow! I went to Apple store at the florida mall to verify if this was normal, brought my old 3G with me so they could notice the difference,so I made the appointment and when the so called "apple genius" saw my phone he noticed the difference and took my phone to change it to the back of the store, he came back in 3 minutes claiming that he changed my phone,when I looked at it,same yellow display I said to the guy that the display looks the same but he never gave me any other option, on my way out from the store i checked the info on the phone but it was the same IMEI as the one in the box, how could this be? if they supposedly change the phone, I asked to speak to a manager and explained to her my situation, the "genius" that "helped me" told the manager that what he did was only changing the display and since I didn't like it,he went back and put back again the display that came with the phone... at this point I got really upset and I asked the manager to speak to the "genius" and asked why he lied about the situation, the manager said that she would bring the guy so we could settle this situation,they left me waiting on the store 45 minutes and none of them showed up... Great Apple store service... Yeah right!! F#$%^ them!

Xperia Z3 display yellow tint at bottom

Hallo to Z3 community! I noticed a yellow tint at the bottom of my screen (little difficult to notice, but it exists). The problem appears when you put the brightness at full with white background (into the display test at service menu). Is it common issue? Do you have it? Although it' s hard to notice it, i don' t want this problem and i must send it for service if i 'm the only one "lucky" with this issue and it is not normal for this screen.. Thank you in advance and sorry for the bad english!

Hello,
I too have the same problem with my Xperia Z3, yellow glow under the soft keys (home / back / task), the halo is very noticeable with white image full screen, when the soft key disappears. with the video we see very little, with black soft key not known anything. I have lollipop 5.0.2. what do you recommend?

White iPhone 4: "Warm" Yellow LCD Tint - Any owners out there with "blue" tint?

Hey,
I just picked up a white GSM iPhone 4 the other day and, upon comparing it to my black GSM iPhone 4 (purchased in June), I noticed that the white iPhone 4's LCD is noticably (and I would say drastically) yellower or "warmer" than that of the black iPhone. I would say the black iPhone's LCD is noticably whiter, bluer, brighter or "cooler" than that of the white iPhone. I definitely prefer the cooler blue LCD to the warmer yellow; the color seems to pop more and whites actually look white, whereas the yellow looks dim and washed out.
Just curious if any other white iPhone owners received units with the blue tint or if they are all yellow. All the pictures in online hands-on reviews of the white unit seemed to have the yellow tint. I've also heard (on iLounge as well as other speculation) that the yellow tint was/is present on the black CMDA iPhones as well and that the yellow is simply a new panel manufacturer that Apple is now sourcing from and that there's nothing that can be done about it - all new phone will have the yellow tint. Hopefully that's not the case.
So, if anyone out there has the cooler LCD on a white unit, please let me know, as if they exist I would love to visit the Apple store to swap mine out for one. The tint is hard to notice unless you have two units side by side, one yellow, one blue. Even a 3GS side by side with a white 4 shows the disparity.
Thanks.

i had the same yellow tint and the problem is very easy to solve , first i cant understand why apple are so useless when it comes to its ios firmware options , so many iphones have been returned to apple because of this problem and a simple tint adjuster would solve this problem .
ok onto how to solve this problem .
first you need to do something apple hate and always block with every upgrade , jailbreaking
simply jailbreak any iphone ( a temporary messure if you do not want this on your phone )
as soon as your iphone is jailbroken install " color profiles "
when you open this option you see colour temperature , adjust it to the tint you like from very warm to very cold ( blueish tone ) as soon as you have the correct tone you like you can then uninstall the jailbreak by reseting the iphone firmware ,
when your iphone has finished restoring you will see the tone you chose is still there and you can finally enjoy your iphone as you want to
why cant apple include this option in the brightness settings is a mystery or plain dumb , apart from letting users set the tone correctly for thier use it would save apple 1000's with all the returns to the apple store.
if an apple ios firmware developer is reading this then try and knock some sense into the apple's firmware dev team , hopefully before the ipad 3 comes out ( as they are bound to screw that one up tone wise again )
i myself find it a joke and poor on apples side to have to jailbreak my iphone to get the screen to display the correct screen tone .
i hope this helps anyone who is having the same too warm tint to solve the problem as it works , no thanks to apple YET
